Description

Impact

This is a SQL Injection vulnerability in the MongoLite Aggregation Optimizer.

Any Cockpit CMS instance running version 2.13.4 or earlier with API access enabled is potentially affected.

Who is impacted:

  • Any deployment where the /api/content/aggregate/{model} endpoint is publicly accessible or reachable by untrusted users.
  • Attackers in possession of a valid read-only API key (the lowest privilege level) can exploit this vulnerability — no admin access is required.

What an attacker can do:

  • Inject arbitrary SQL via unsanitized field names in aggregation queries.
  • Bypass the _state=1 published-content filter to access unpublished or restricted content.
  • Extract unauthorized data from the underlying SQLite content database.

Confidentiality impact is High. Integrity and availability are not directly affected by this vulnerability.

Patches

This vulnerability has been patched in version 2.13.5.

All users running Cockpit CMS version 2.13.4 or earlier are strongly advised to upgrade to 2.13.5 or later immediately.

The fix applies the same field-name sanitization introduced in v2.13.3 for toJsonPath() to the toJsonExtractRaw() method in lib/MongoLite/Aggregation/Optimizer.php, closing the injection vector in the Aggregation Optimizer.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cockpit-hq/cockpit, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update cockpit-hq/cockpit to 2.13.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-31891 is resolved across your whole dependency graph.

  3. Workarounds

    Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
