Vulnerability from github – Published: 2026-08-28 18:01 – Updated: 2026-08-28 18:03

Summary

Snipe-IT vulnerable to directory traversal in displaySig

Details

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.

Reported by https://github.com/securin-public

Severity

7.1 (High)

CVE-2026-55474 (GCVE-0-2026-55474)

Vulnerability from cvelistv5 – Published: 2026-07-10 18:29 – Updated: 2026-07-10 19:12

Title

Snipe-IT: Directory traversal in displaySig

Summary

Snipe-IT is an IT asset/license management system. Prior to 8.5.0, ActionlogController::displaySig concatenates the route filename parameter into a private upload-directory path without sanitization, allowing an authenticated attacker to traverse outside the intended directory and read arbitrary files accessible to the web server process. This issue is fixed in version 8.5.0.

Severity

7.1 (High)
