CKAN: Unauthenticated SQL Injection and Authorization Bypass in `datastore_search_sql`
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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.
Real-World Exposure
ckan🐍ckanReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Impact
A vulnerability in datastore_search_sql allowed attackers to inject SQL 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 a project's DataStore and the likelihood of abuse of a consuming site, a developer may choose to disable this action function or restrict its use with a IAuthFunctions plugin.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update ckan to 2.10.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-42031 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-2026-42031 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-42031. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
