Description

Impact

A vulnerability in datastore_search_sql allowed attackers to bypass authorization in order to gain access to private resources and PostgreSQL system information

Patches

The issue has been patched in CKAN 2.10.10 and CKAN 2.11.5

Workarounds

Disable the DataStore SQL search (ckan.datastore.sqlsearch.enabled = false). Note that the SQL search is disabled by default.

More information

As stated in the documentation, this action function has protections that offer some safety but are not designed to prevent all types of abuse. Depending on the sensitivity of private data in your DataStore and the likelihood of abuse of your site, you may choose to disable this action function or restrict its use with a IAuthFunctions plugin.

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update ckan to 2.10.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-42032 is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-42032 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2026-42032. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
