CVE-2022-50939Public exploitNetwork attack vector

Administrator code execution via traversed upload caption

Published Jan 13, 2026 · Updated Jan 13, 2026

Path traversal in e107 CMS 3.2.1 allows remote authenticated administrators to overwrite server files through Media Manager imports. The image.php import path uses upload_caption as a destination filename without removing ../ sequences, so a fetched remote file escapes the media directory. Administrative access is required; placing executable PHP in the web root enables server-side code execution or replacement of application files.
