CVE-2026-6262Network attack vector

Arbitrary file deletion via unconstrained upload path

Published May 5, 2026 · Updated May 5, 2026

Path traversal in Muffin Group Betheme 28.4 and earlier allows remote authenticated users to delete arbitrary local files. The upload_icons() workflow passes the user-controlled mfn-icon-upload path to a filesystem move operation without restricting resolution to the uploads directory. Contributor-level access is sufficient, and traversal outside that directory permits deletion of files writable by the WordPress process.
