GeoTools has unauthenticated SQL injection in the jsonArrayContains filter function against PostGIS layers

Critical severity GitHub Reviewed Published Aug 15, 2026 in geotools/geotools • Updated Aug 21, 2026

Package

maven org.geotools.jdbc:gt-jdbc-postgis (Maven)

Affected versions

Description

Summary

An SQL Injection Vulnerability has been found when executing OGC Filters with PostGIS DataStore implementation:

  • jsonArrayContains function
    Requires PostGIS 12 or greater with a String or JSON field

For PostGIS 12 and greater jsonArrayContains(<column>, <pointer>, <value>) function writes <value> into generated SQL without escaping.

Patches

  • GeoTools 35.1
  • GeoTools 33.5
  • GeoTools 34.4

Mitigation

No mitigation is available:

  • To limit scope of SQL Injection the PostGIS connection pool should be configured with limited rights.

Impact

This vulnerability can lead to execution of arbitrary SQL expressions in the database.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
