Snipe-IT vulnerable to directory traversal in displaySig
Quick fix
GHSA-c6f4-wj38-m3g3 — snipe/snipe-it: upgrade to the fixed version with the command below.
composer require snipe/snipe-it:^8.5.0Details
### Impact 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.
