VulnerabilityCVE-2023-32321

Ckan remote code execution and private information access via crafted resource ids

Specific vulnerabilities: * Arbitrary file write in `resource_create` and `package_update` actions, using the `ResourceUploader` object. Also reachable via `package_create`, `package_revise`, and `package_patch` via calls to `package_update`.

What happened

Specific vulnerabilities:

* Arbitrary file write in `resource_create` and `package_update` actions, using the `ResourceUploader` object. Also reachable via `package_create`, `package_revise`, and `package_patch` via calls to `package_update`. * Remote code execution via unsafe pickle loading, via Beaker's session store when configured to use the file session store backend. * Potential DOS due to lack of a length check on the resource id.

* Information disclosure: A user with permission to create a resource can access any other resource on the system if they know the id, even if they don't have access to it. * Resource overwrite: A user with permission to create a resource can overwrite any resource if they know the id, even if they don't have access to it.

### Impact

Continue reading

A user with permissions to create or edit a dataset can upload a resource with a specially crafted id to write the uploaded file in an arbitrary location. This can be leveraged to Remote Code Execution via Beaker's insecure pickle loading.

### Patches

All the above listed vulnerabilities have been fixed in CKAN 2.9.9 and CKAN 2.10.1 The patches for CKAN 2.9 should apply easily to previous CKAN versions.

Affected package ranges reported by GitHub: ckan: < 2.9.9 ckan: = 2.10.0

About this data

This record was ingested from a data source. Retrieved: Oct 27, 2026, 17:25 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
