CVE-2026-45260 pimcore CVE debrief

Who should care

Users of Pimcore, especially those using WebDAV asset endpoints, should be aware of this vulnerability and take steps to mitigate it. This includes administrators, security teams, and developers who work with Pimcore. They should review the official advisory and take steps to update Pimcore to versions 11.5.17 (LTS) or 12.3.7, or later. Additionally, they should restrict access to the WebDAV asset endpoint and monitor for suspicious activity.

Technical summary

The vulnerability exists in Pimcore's WebDAV asset endpoint, specifically in the /asset/webdav{path} path. The MOVE operation is exposed without an authentication plugin, allowing unauthorized asset deletion, moves, or overwrites. This is due to the lack of authentication checks in bundles/CoreBundle/src/Controller/WebDavController.php and models/Asset/WebDAV/Tree.php before performing asset mutation and deletion through models/Asset.php. The issue is fixed in versions 11.5.17 (LTS) and 12.3.7.

Defensive priority

High priority should be given to updating Pimcore to versions 11.5.17 (LTS) or 12.3.7, or later. Additionally, defenders should review and restrict access to the WebDAV asset endpoint, monitor for suspicious activity, and review compensating controls for exposed systems.

Recommended defensive actions

• Update Pimcore to version 11.5.17 (LTS) or 12.3.7, or later
• Review and restrict access to the WebDAV asset endpoint
• Monitor for suspicious activity on the WebDAV asset endpoint
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
