1611-1611: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Extend port-security coverage to the status conversion path.

This test exercises Convert_*_ResolvedPortSpecFields_* directly, so it passes. No test converts an OpenStackMachineStatus or BastionStatus that carries Resolved.Ports[].DisablePortSecurity. That gap is why the unsafe.Pointer casts at lines 220, 250, 273, and 286 of api/v1beta1/conversion.go go undetected.

Add a case that sets Status.Resolved.Ports[0].DisablePortSecurity on a v1beta1 OpenStackMachine, converts to the hub, and asserts EnablePortSecurity is inverted.

TestResolvedPortSpecFields_RoundTrip_PortSecurity only covers direct field
conversion; extend conversion-test coverage to convert a v1beta1
OpenStackMachine with Status.Resolved.Ports[0].DisablePortSecurity set, then

Inline comments:
In @.github/workflows/pr-dependabot.yaml:
- Line 25: Restrict the credentialed workflow job containing persist-credentials
to Dependabot-authored pull requests and Dependabot pushes, rather than relying
on pull_request.branches; ensure workflow_dispatch remains excluded or is
guarded by the same condition. Keep only the permissions required for
committing, and preserve the existing job behavior for allowed Dependabot
events.

In `@api/v1beta1/conversion.go`:
- Line 220: Replace the unsafe Bastion and Resolved casts in the cluster and
machine status conversion methods with the existing generated BastionStatus and
ResolvedMachineSpec converters. Preserve nil handling and return any conversion
errors so nested ResolvedPortSpec conversions apply the v1beta1/v1beta2
port-security inversion.

In `@api/v1beta2/types.go`:
- Line 1057: Update the four kubebuilder default markers in the monitor type to
use assignment syntax so they emit API-schema default entries, then regenerate
the checked-in CRD using the repository’s standard generation process. Preserve
the existing default values of 10, 5, 5, and 3 and the ensureMonitor behavior.

In `@CONTRIBUTING.md`:
- Line 63: Update the minor-release support table in CONTRIBUTING.md to include
v0.15.x with its existing v1beta2 and v1beta1 support status, and add the
corresponding supported-until date required by the documented policy.

In `@controllers/openstackfloatingippool_controller.go`:
- Around line 209-213: Remove the explicit status update following the
conditions.Set call in the reconcile flow, while retaining the Ready condition
assignment. Let the existing deferred patch mechanism detect and persist the
status change, and preserve the surrounding error handling and reconcile
behavior.

In `@Dockerfile`:
- Line 17: Update the builder stage’s FROM instruction to pin each supported Go
version to its approved Docker image digest instead of using the mutable golang
version tag, while preserving the existing GO_VERSION selection behavior.

In `@docs/book/src/clusteropenstack/configuration.md`:
- Line 311: Correct the v1beta2 manifest field paths in
docs/book/src/clusteropenstack/configuration.md: at lines 311-311, change
OpenStackCluster.spec.APIServer.enableFloatingIP to
OpenStackCluster.spec.apiServer.enableFloatingIP; at lines 341-341, change
spec.APIServer.ManagedLoadBalancer.AllowedCIDRs to
spec.apiServer.managedLoadBalancer.allowedCIDRs. No other changes are needed.

In `@docs/book/src/topics/crd-changes/v1beta1-to-v1beta2.md`:
- Line 274: Update the Go example imports to include the metav1 package used by
metav1.ConditionTrue, while retaining the existing meta import if it is still
referenced.

In `@go.mod`:
- Line 153: Update the google.golang.org/grpc dependency from v1.82.1 to v1.83.1
or later, then regenerate the vendored dependencies so vendor/modules.txt and
related vendor contents match the upgraded version.

In `@main.go`:
- Line 111: Update the scheme registration near infrav1beta1.AddToScheme to
handle its error instead of discarding it, using the existing error-propagation
pattern or utilruntime.Must so manager initialization cannot continue with an
incomplete scheme.

In `@pkg/cloud/services/networking/network.go`:
- Around line 289-291: Update the ReplaceAllAttributesTags calls in
pkg/cloud/services/networking/network.go lines 289-291 and
pkg/cloud/services/networking/router.go lines 213-215 to assign the returned
tags to subnet.Tags and router.Tags respectively, while preserving existing
error handling.

In `@pkg/webhooks/openstackcluster_webhook.go`:
- Around line 284-286: Update securityGroupRemoteFields to determine whether
RemoteManagedGroups is set by checking its length rather than only whether it is
non-nil, while preserving the existing presence checks for RemoteGroupID and
RemoteIPPrefix.

In `@releasenotes/v0.14.6.md`:
- Line 3: Update the release-notes heading under the v0.14.6 release to state
that changes are measured since v0.14.5, preserving the existing heading format.

In `@releasenotes/v0.15.0-alpha.0.md`:
- Line 30: Correct the linter name from “intergers” to “integers” in
releasenotes/v0.15.0-alpha.0.md lines 30-30, releasenotes/v0.15.0-beta.0.md
lines 30-30, and releasenotes/v0.15.0-rc.0.md lines 30-30.

In `@test/e2e/shared/suite.go`:
- Line 74: Update the deferred cleanup around templatesDirRoot.Close in the test
setup to capture its returned error and assert or report it using the test’s
existing error-handling mechanism, rather than discarding it.
- Line 78: Update the filepath.WalkDir callback in the E2E setup flow to return
the callback’s incoming error before accessing the fs.DirEntry parameter.
Preserve the existing d.IsDir() processing for successful traversal callbacks,
preventing nil-entry dereferences when traversal fails.

In `@test/e2e/suites/e2e/clusterctl_upgrade_test.go`:
- Around line 250-253: Update the ORC manifest download around
http.DefaultClient.Do in the upgrade test to enforce a finite deadline using
context.Context, ensuring both callers cannot hang indefinitely while preserving
the existing request and response cleanup behavior.

In `@test/e2e/suites/e2e/e2e_test.go`:
- Line 1269: Update the polling function around DumpOpenStackPorts to capture
and return its error instead of discarding it, so OpenStack API failures
propagate immediately rather than appearing as timeouts. Preserve the existing
portList assignment and polling behavior on successful calls.

💡 Result:

<search_synthesis>
In GitHub Actions, you can control which pull requests trigger a workflow by using the branches filter within the pull_request event configuration [1][2]. This filter operates against the base branch—the branch that the pull request is targeting [1][2]. Workflow Filter Configuration: You can specify the target base branches using the branches key, which supports glob patterns [2][3]. on: pull_request: branches: - main - &#39;releases/&#39; If you need to both include and exclude branches, use the branches filter with the! character to denote exclusions, as you cannot use branches and branches-ignore simultaneously for the same event [2][3]. Security and GITHUB_TOKEN Permissions: When a pull request originates from a fork, GitHub applies security restrictions to the GITHUB_TOKEN to protect the repository from unauthorized code execution [4]. 1. pull_request Event: Workflows triggered by the pull_request event run using the code from the pull request&#39;s merge commit [4]. Because this code is untrusted, GitHub restricts the GITHUB_TOKEN to read-only permissions and denies access to repository secrets [4]. 2. pull_request_target Event: If you require elevated permissions (such as access to secrets) for pull requests from forks, the pull_request_target event is used [4]. This event executes the workflow file from the base repository&#39;s default branch rather than the fork&#39;s branch, making it safer to grant read/write access and secrets [4]. Regardless of the event, you should always explicitly define the minimum required permissions for your GITHUB_TOKEN using the permissions key at the workflow or job level to follow security best practices [5]. permissions: contents: read # Add other necessary permissions here You can also use the GITHUB_BASE_REF environment variable within your workflow steps to programmatically identify the target base branch of the pull request [6].

This is the same trust given to events like `push` that only collaborators can trigger, and it is what makes `pull_request_target` useful for automation that responds to pull requests from forks, such as labeling, triage, or for posting authenticated status checks. ... The `pull_request` event (along with `pull_request_review` and `pull_request_review_comment`) is unusual: it runs the workflow file from the merge commit of the pull request. For a pull request opened from a fork, that commit is controlled by someone without write access to the base repository. To run untrusted workflow code safely, GitHub restricts these events to a read-only `GITHUB_TOKEN`, withholds access to other secrets, and applies fork approval policies to prevent compute abuse. For more information, see Events that trigger workflows. By default, `actions/checkout` in a `pull_request` workflow also checks out the pull request&`#39`;s merge commit, so the code checked out and the workflow that runs are consistent. ... `pull_request_target` makes one critical and subtle change: the workflow, and any subsequent `actions/checkout` call that does not specify a `ref`, is taken from the base repository&`#39`;s default branch, not from the pull request. Because only trusted code from the default branch runs, it is safe to grant secrets and a read/write token. No code from the fork is executed by default. ... - Can you use `pull_request` instead? `pull_request` triggers on the same events as `pull_request_target` and runs the workflow code from the `pull_request` merge branch. It does this safely on pull requests from forks with the protections detailed above. If additional secret access is not needed, use `pull_request`. More complex workflows can be restructured to separate potentially dangerous handling of pull request code from accessing secrets. For more information, see Preventing pwn requests from the GitHub Security Lab. ... - Restrict secrets. Confirm that the permissions set on the `GITHUB_TOKEN` have the least privileges and that only the necessary repository and organization secrets are used for the workflow. For more information, see Use GITHUB_TOKEN for authentication in workflows. ... - Understand the impact to caching. To reduce the risk of cache poisoning, workflows triggered by `pull_request_target` have read-only access to the cache in the default branch&`#39`;s scope. These workflows can restore existing cache entries but cannot create or overwrite them, so they cannot affect the execution of other, unrelated, workflows through the shared cache. If such a workflow attempts to save a cache, the save fails but the step and the job continue, and the failure is reported as a warning in the workflow log. If your workflow needs to populate the cache, save it from a workflow that runs on a trusted trigger such as `push`. For more information, see Dependency caching reference. ... If you have worked through the questions above and confirmed your workflow requires `pull_request_target` and uses it safely, you can opt out of the `actions/checkout` protection. Setting `allow-unsafe-pr-checkout: true` as an `actions/checkout` input allows checking out pull request head refs from forks. Only do this after confirming the checked-out code is never executed. The input is intentionally named to be easy to spot in code review and static analysis. ... This protection only covers fork pull request refs. Checking out other untrusted code, such as an unrelated third-party repository, fetching code with `git fetch` or `gh pr checkout`, or running a downloaded artifact, is not covered by the `actions/checkout` checks. <title>Result 5</title> https://docs.github.com/en/actions/tutorials/authenticate-with-github_token # Use GITHUB_TOKEN for authentication in workflows Learn how to use the GITHUB_TOKEN to authenticate on behalf of GitHub Actions. This tutorial leads you through how to use the `GITHUB_TOKEN` for authentication in GitHub Actions workflows, including examples for passing the token to actions, making API requests, and configuring permissions for secure automation. For reference information, see Workflow syntax for GitHub Actions. ## Using the `GITHUB_TOKEN` in a workflow You can use the `GITHUB_TOKEN` by using the standard syntax for referencing secrets: `${{ secrets.GITHUB_TOKEN }}`. Examples of using the `GITHUB_TOKEN` include passing the token as an input to an action, or using it to make an authenticated GitHub API request. > [!IMPORTANT] > An action can access the `GITHUB_TOKEN` through the `github.token` context even if the workflow does not explicitly pass the `GITHUB_TOKEN` to the action. As a good security practice, you should always make sure that actions only have the minimum access they require by limiting the permissions granted to the `GITHUB_TOKEN`. For more information, see Workflow syntax for GitHub Actions. ### Example 1: passing the `GITHUB_TOKEN` as an input This example workflow uses the GitHub CLI, which requires the `GITHUB_TOKEN` as the value for the `GH_TOKEN` input parameter: ```yaml copy name: Open new issue on: workflow_dispatch jobs: open-issue: runs-on: ubuntu-latest permissions: contents: read issues: write steps: - run: | gh issue --repo ${{ github.repository }} \ create --title "Issue title" --body "Issue body" env: GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} ``` ### Example 2: calling the REST API You can use the `GITHUB_TOKEN` to make authenticated API calls. This example workflow creates an issue using the GitHub REST API: ```yaml name: Create issue on commit on: [ push ] jobs: create_issue: runs-on: ubuntu-latest permissions: issues: write steps: - name: Create issue using REST API run: | curl --request POST \ --url https://api.github.com/repos/${{ github.repository }}/issues \ --header &`#39`;authorization: Bearer ${{ secrets.GITHUB_TOKEN }}&`#39`; \ --header &`#39`;content-type: application/json&`#39`; \ --data &`#39`;{ "title": "Automated issue for commit: ${{ github.sha }}", "body": "This issue was automatically created by the GitHub Action workflow **${{ github.workflow }}**. \n\n The commit hash was: _${{ github.sha }}_." }&`#39`; \ --fail ``` ## Modifying the permissions for the `GITHUB_TOKEN` Use the `permissions` key in your workflow file to modify permissions for the `GITHUB_TOKEN` for an entire workflow or for individual jobs. This allows you to configure the minimum required permissions for a workflow or job. As a good security practice, you should grant the `GITHUB_TOKEN` the least required access. To see the list of permissions available for use and their parameterized names, see Managing your personal access tokens. The two workflow examples earlier in this article show the `permissions` key being used at the job level. ## Granting additional permissions If you need a token that requires permissions that aren&`#39`;t available in the `GITHUB_TOKEN`, create a GitHub App and generate an installation access token within your workflow. For more information, see Making authenticated API requests with a GitHub App in a GitHub Actions workflow. Alternatively, you can create a personal access token, store it as a secret in your repository, and use the token in your workflow with the `${{ secrets.SECRET_NAME }}` syntax. For more information, see Managing your personal access tokens and Using secrets in GitHub Actions. ## Next steps - GITHUB_TOKEN - Workflow syntax for GitHub Actions

Use the generated converters for nested status values.

The cluster status converters cast Bastion directly, and the machine status converters cast Resolved directly. These values reach ResolvedMachineSpec.Ports[].ResolvedPortSpecFields, where v1beta1 uses DisablePortSecurity and v1beta2 uses EnablePortSecurity.

The generated ResolvedPortSpec converters invoke the custom inversion converters. The unsafe.Pointer casts skip them. A v1beta1 status with DisablePortSecurity: true can therefore produce a v1beta2 status with EnablePortSecurity: true. This makes the converted status report the wrong port-security state. It does not, by itself, change the OpenStack port.

Replace the casts with the existing Convert_v1beta1_BastionStatus_*, Convert_v1beta2_BastionStatus_*, Convert_v1beta1_ResolvedMachineSpec_*, and Convert_v1beta2_ResolvedMachineSpec_* calls. Preserve nil handling and propagate conversion errors.

Use assignment syntax for the four default markers and regenerate the CRD.

The +kubebuilder:default:... markers do not produce default entries in the checked-in CRD schema. Omitted monitor properties remain absent after admission and decode as Go zero values. However, ensureMonitor replaces those zero values with 10, 5, 5, and 3 before creating or updating the load-balancer monitor.

Return the WalkDir callback error before using d.

When traversal fails, filepath.WalkDir can call this function with d == nil. The current code ignores that error and then calls d.IsDir() on Line 81. This panics instead of reporting the E2E setup failure.

Proposed fix

OSV google.golang.org/grpc v1.82.1 v1.83.1 vulnerability fixed version

💡 Result:

<search_synthesis>
The vulnerability regarding heap memory exhaustion (OOM) via HTTP/2 DATA frame fragmentation in google.golang.org/grpc (gRPC-Go) was addressed in version v1.83.1 [1][2]. Specifically: - Vulnerability: An unauthenticated remote attacker could trigger heap memory exhaustion by sending fragmented HTTP/2 DATA frames [1][2]. This could lead to a remote Denial of Service (DoS) [1][2]. - Affected Versions: All versions up to and including v1.83.0 are affected [1]. - Fixed Version: v1.83.1 contains the fix [1][2]. - Reference: This issue is tracked as GitHub Advisory GHSA-vp52-pcj8-j9qc (and associated with CVE-2026-84304) [1][2]. Users are encouraged to upgrade to v1.83.1 or newer to mitigate this risk [1]. The fix introduces receive buffer compaction, which is enabled by default [1]. Note: Another recent advisory, GHSA-hrxh-6v49-42gf, addressed earlier vulnerabilities in the xDS RBAC engine and HTTP/2 transport, which were fixed in v1.82.1 [3][4][5]. If you are currently on a version older than v1.83.1, upgrading to v1.83.1 will also include the fixes from v1.82.1 [1].

Even if the total payload volume falls within the configured connection and stream flow-control windows, each independent fragment incurs memory overhead due to internal tracking structures and queue allocation. Repeated fragmentation massively inflates the heap space consumed by the stream. An attacker multiplexing multiple concurrent streams can exhaust the memory bounds of the runtime, forcing a runtime panic or OutOfMemory condition and leading to a remote Denial of Service (DoS). ### Patches The change to fix this issue is merged in `master` and a patch release, 1.83.1, has been published that contains this fix. ### Workarounds This vulnerability is mitigated by implementing receive buffer compaction. Consecutive small data buffers are automatically coalesced into larger buffers from a shared pool once the overhead is perceived to be excessive relative to actual payload data, drastically minimizing per-frame memory overheads. This behavior is enabled by default. A temporary escape hatch is provided via the environment variable `GRPC_GO_EXPERIMENTAL_ENABLE_RECEIVE_BUFFER_COMPACTION=false` to disable the feature if unforeseen issues arise, but it will be removed in a future release. ### Severity High ### CVE ID No known CVE ### Weaknesses Weakness CWE-400 #### Uncontrolled Resource Consumption The product does not properly control the allocation and maintenance of a limited resource.

These vulnerabilities could result in: - Authorization Bypass (Fail-Open) when translating xDS RBAC policies containing`Metadata` or`RequestedServerName` fields. - Denial of Service (High CPU Consumption) due to an HTTP/2 Rapid Reset mitigation bypass during client-initiated stream resets. - Denial of Service (Server Panic) when parsing crafted xDS RBAC policies containing`NOT` rules around unsupported fields. ### Impact What kind of vulnerability is it? Who is impacted? #### xDS RBAC Authorization Bypass via Metadata & RequestedServerName matchers - Affected Component: xDS RBAC - Impact: When building policy matchers for gRPC RBAC from xDS configurations, unsupported`permission` and`principal` rules (specifically`Metadata` and`RequestedServerName`) were silently ignored and treated as no-ops. - - If an authorization policy relied purely on these matchers for access control, treating those rules as no-ops effectively removed the restrictions. - If these unsupported rules were nested inside logical`NOT` rules (`Permission_NotRule`/`Principal_NotId`) or multi-condition`OR/AND` rules, silently dropping them changed the boolean logic flow of the authorization engine. As a result, policy evaluation decisions could fail open, allowing unauthorized clients to access protected gRPC services or resources. #### HTTP/2 Rapid Reset Mitigation Bypass / Denial of Service via Stream Aborts - Affected Component: HTTP/2 transport - Impact: Earlier mitigations in grpc-go for HTTP/2 Rapid Reset only applied threshold checks to items that directly resulted in control frames being written back to the wire, such as`SETTINGS` ACKs or server-initiated`RST_STREAM` s. When a client initiated a rapid flood of stream creation (`HEADERS`) immediately followed by stream termination`RST_STREAM`, items queued up in the control buffer without counting against the transport response frame threshold. An attacker can repeatedly trigger this flood sequence to bypass reader blocking, resulting in high CPU usage, and Denial of Service (DoS). #### Denial of Service (Panic) in xDS RBAC Engine via Unsupported Fields inside NOT Rules - Affected Component: xDS RBAC - Impact: The xDS RBAC policy translators recursively generate matchers for nested rules. When a`NOT` rule wrapped an unsupported or unhandled field (such as`SourcedMetadata`), the recursive step returned an empty matcher. This could result in a runtime panic when the RBAC engine attempts to authorize an incoming request. An attacker or misconfigured/malicious xDS management server delivering an LDS/RDS update containing a`NOT` rule around an unhandled field causes the gRPC server process to crash immediately (CWE-248 / Denial of Service). ### Patches Has the problem been patched? What versions should users upgrade to? All three issues have been fixed in`master` and will be released in 1.82.1 shortly. ### Workarounds Is there a way for users to fix or remediate the vulnerability without upgrading? If upgrading grpc-go immediately is not possible, apply the following workarounds based on your deployment architecture: - For xDS RBAC Vulnerabilities & Panics: Ensure that upstream xDS management servers do not push RBAC policies containing`Metadata`,`RequestedServerName`, or`NOT` rules wrapping unsupported fields (such as`SourcedMetadata`) to grpc-go servers. - For HTTP/2 Rapid Reset DOS: Configure upstream reverse proxies or load balancers (such as Envoy) with strict HTTP/2`max_concurrent_streams` limits and active rat…[truncated] <title>gRPC-Go: xDS RBAC and HTTP/2 Vulnerabilities · GHSA-hrxh-6v49-42gf · GitHub Advisory Database · GitHub</title> https://github.com/advisories/GHSA-hrxh-6v49-42gf google.golang.org/grpc (Go) ... ## Affected versions ... < 1.82.1 ... ## Patched versions ... 1.82.1 ... ### Patches ...
