EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 65% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
