Admidio before 5.0.12 Path Traversal via Photo ZIP Download

Assigner: VulnCheck
Reserved: 30.08.2026 Published: 30.08.2026 Updated: 30.08.2026

Admidio before 5.0.12 fails to sanitize album names in the photo ZIP download functionality, allowing authenticated users with album-creation rights to include path traversal segments in archive entry names. Attackers can craft malicious album names containing directory traversal sequences that escape the intended directory when recipients extract the archive, potentially writing files outside the target directory.
