GHSA-C6F4-WJ38-M3G3
Vulnerability from github – Published: 2026-08-28 18:01 – Updated: 2026-08-28 18:03Impact
The displaySig action in ActionlogController serves signature image files from a private upload directory. The filename parameter from the HTTP route is concatenated directly into a filesystem path with no sanitization, allowing an authenticated attacker to traverse outside the intended directory and read arbitrary files accessible to the web server process.
