EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2026-31891 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,636 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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_state=1published-content filter to access unpublished or restricted content.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 dependencyDetect
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.
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.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-31891 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-31891. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-31891 in your dependencies?
O3 Security finds CVE-2026-31891 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
