CVE-2026-76904: Technical Details & Mitigation

What is CVE-2026-76904 and which software versions are affected?

CVE-2026-76904 is a critical unauthenticated SQL injection vulnerability in GeoTools, an open-source geospatial data library used by GeoServer and other GIS applications. The flaw exists in the jsonArrayContains OGC filter function of the PostGIS DataStore implementation, where user input is concatenated into SQL statements without sanitization. Affected versions include GeoTools 30.5 up to 33.5, 34.0 up to 34.4, and 35.0. Applications bundling these GeoTools versions with a PostGIS datastore (notably GeoServer builds) inherit this vulnerability when PostGIS 12 or later is in use. Note: Only environments meeting these criteria are affected; other configurations are not impacted.

What is the severity and potential impact of CVE-2026-76904?

CVE-2026-76904 carries a CVSS v3.1 base score of 9.8 (Critical). The vulnerability allows unauthenticated, remote attackers to execute arbitrary SQL statements, potentially escalating to remote code execution if the database connection has elevated privileges. This can result in full compromise of confidentiality, integrity, and availability of the backing database. Note: The vulnerability is a regression of CVE-2023-25158 and is specific to the jsonArrayContains function; previous mitigations do not prevent this issue.

How can organizations mitigate or remediate CVE-2026-76904?

The recommended mitigation is to upgrade to patched GeoTools releases: 33.6, 34.5, or 35.1 (or later). GeoServer users should upgrade to GeoServer 2.27.6, 2.28.5, or 3.0.1. If immediate patching is not possible, restrict database privileges (avoid superuser or program-execution rights), limit network exposure of affected services, and monitor database logs for anomalous queries. Note: No complete workaround exists; these steps reduce risk but do not eliminate the vulnerability. Full remediation requires patching.

New CVE Detected

CVE-2026-76904 – Unauthenticated SQL Injection (leading to potential RCE) – GeoTools 30.5–33.5, 34.0

Be the first to know when new zero-days emerge:

Summary

CVE-2026-76904 is a critical, unauthenticated SQL injection vulnerability in GeoTools, the open-source geospatial data library used by GeoServer and other GIS applications. The flaw resides in the jsonArrayContains OGC filter function of the PostGIS DataStore implementation, where a user-controlled value is concatenated directly into a generated SQL statement without sanitization. Because the vulnerability requires no authentication or user interaction and can be triggered over the network, it carries a CVSS v3.1 score of 9.8 (Critical), and depending on database privileges it can escalate to remote code execution.

Technical details

  • Root cause: The jsonArrayContains(<column>, <pointer>, <value>) filter function, implemented in the PostGIS filter-to-SQL translation logic (gt-jdbc-postgis module), writes the <value> parameter into the generated SQL query without escaping or parameterization.
  • Trigger conditions: Exploitable only when GeoTools/GeoServer is backed by a PostGIS datastore running PostGIS 12 or later, with a layer containing a String or JSON-typed field that can be targeted via an OGC Filter using jsonArrayContains.
  • Attack vector: Network-based; an attacker sends a crafted OGC filter request (e.g., via WFS/WMS requests handled by GeoServer or any application embedding the vulnerable GeoTools module) containing malicious SQL in the <value> argument.
  • Impact: Full compromise of confidentiality, integrity, and availability of the backing database. This is a regression of the earlier CVE-2023-25158 issue, specific to the jsonArrayContains function — the previous mitigation (enabling prepared statements and disabling encode functions) does not prevent this vulnerability. If the database connection used by GeoServer/GeoTools has elevated privileges (e.g., PostgreSQL superuser or a role with program-execution rights), the flaw can be leveraged to achieve operating system command execution.

Affected software

  • GeoTools versions 30.5 up to 33.5
  • GeoTools versions 34.0 up to 34.4
  • GeoTools version 35.0
  • Applications and platforms bundling these GeoTools versions with a PostGIS datastore (notably GeoServer builds incorporating the affected GeoTools releases) inherit this vulnerability when PostGIS 12+ is in use.

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade to the patched GeoTools releases: 33.6, 34.5, or 35.1 (or later). Users running GeoServer should upgrade to the corresponding fixed distributions: GeoServer 2.27.6, 2.28.5, or 3.0.1.
  • If patching cannot be applied immediately: The official advisory states no complete workaround exists — configuring the PostGIS database connection pool to use a role with the minimum necessary privileges (avoiding superuser or program-execution rights) can reduce the potential impact if exploitation occurs, but does not close the injection itself. Restricting network exposure of GeoServer/GeoTools instances and monitoring database logs for anomalous queries against PostGIS-backed layers is also recommended until patches are applied.
