How to Fix CVE-2026-42032

To remediate this vulnerability, upgrade all affected Ckan dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ckan fixed: 2.10.10

pip install ckan>=2.10.10

ckan fixed: 2.11.5

pip install ckan>=2.11.5

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

pip show ckan

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-42032, inspect your installed packages using pip:

pip show ckan

Analyze the terminal output to locate any version of Ckan in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.10.10), your application is affected.

Note: The pip show ckan command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Ckan, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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](https://docs.ckan.org/en/2.11/maintaining/configuration.html#ckan-datastore-sqlsearch-enabled), 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`](https://docs.ckan.org/en/2.11/extensions/plugin-interfaces.html#ckan.plugins.interfaces.IAuthFunctions) plugin. ### Credits * Reported by Arvin Shivram of Brutecat Security
