Unauthenticated Asset Deletion in Pimcore

Publication date: 2026-07-17

Last updated on: 2026-07-17

Assigner: GitHub, Inc.

Description
Pimcore is an Open Source Data & Experience Management Platform. Prior to 11.5.17 (LTS) and 12.3.7, Pimcore's WebDAV asset endpoint exposes a MOVE operation through /asset/webdav{path} without an authentication plugin in bundles/CoreBundle/src/Controller/WebDavController.php, and models/Asset/WebDAV/Tree.php performs asset mutation and deletion through models/Asset.php before checking a current Pimcore user or the rename, delete, create, or publish permissions, allowing unauthorized asset deletion, moves, or overwrites. This issue is fixed in versions 11.5.17 (LTS) and 12.3.7.

Executive Summary

CVE-2026-45260 is a missing authorization vulnerability in Pimcore's WebDAV MOVE operation. It allows unauthorized users to delete, move, or overwrite assets without proper permission checks. The issue occurs because the WebDAV controller does not enforce authentication before processing MOVE requests, and asset mutations are performed before verifying user permissions.

Detection Guidance

Check Pimcore version with: composer show pimcore/pimcore. If version is <=11.5.16 or <=12.3.6, the system is vulnerable. Inspect WebDAV logs for unauthorized MOVE requests to /asset/webdav{path}.

Impact Analysis

This vulnerability can lead to unauthorized asset deletion, overwrites, or moves, causing data loss, content integrity issues, and service disruption. Attackers with knowledge of asset paths can exploit it to manipulate or delete critical assets without authentication.

Compliance Impact

This vulnerability could lead to unauthorized asset deletion, overwrites, or moves, potentially violating data integrity and confidentiality requirements under GDPR and HIPAA. Unauthorized modifications may result in unauthorized access to personal or sensitive data, breaching compliance with data protection regulations.

Mitigation Strategies

Upgrade Pimcore to version 11.5.17 (LTS) or 12.3.7 or later. If immediate upgrade is not possible, restrict access to WebDAV endpoints via firewall or disable WebDAV if unused.
