Description
CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Using a specially crafted file, a user could potentially upload a file containing code that when executed could send arbitrary requests to the server. If that file was opened by an administrator, it could lead to escalation of privileges of the original submitter or other malicious actions. Users must have been registered to the site to exploit this vulnerability. This vulnerability has been fixed in CKAN 2.10.7 and 2.11.2. Users are advised to upgrade. On versions prior to CKAN 2.10.7 and 2.11.2, site maintainers can restrict the file types supported for uploading using the ckan.upload.user.mimetypes / ckan.upload.user.types and ckan.upload.group.mimetypes / ckan.upload.group.types config options. To entirely disable file uploads users can use: ckan.upload.user.types = none

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 2.10.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-24372 is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
