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

CVE-2026-76904GHSA-mqjf-5f49-2fjh

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.geotools.jdbc:gt-jdbc-postgis 35.1, 34.5, 33.6), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2026-76904

Advisory: GeoTools has unauthenticated SQL injection in the jsonArrayContains filter function against PostGIS layers
IDs: CVE-2026-76904, GHSA-mqjf-5f49-2fjh
Record: https://patchnext.com/advisories/cve-2026-76904 (revision 2, source checked 26 Oct 2026, 16:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.geotools.jdbc:gt-jdbc-postgis 35.1, 34.5, 33.6. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.geotools.jdbc:gt-jdbc-postgis: affected >= 35.0, <= 35.0; >= 34.0, < 34.5; >= 30.5, < 33.6; fixed in 35.1, 33.6, 34.5

## Suggested inspection (read-only)
- Maven org.geotools.jdbc:gt-jdbc-postgis: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.geotools.jdbc:gt-jdbc-postgis.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
