CVE-2021-3858Public exploitNetwork attack vector

Unauthorized record restoration via GET restore routes

Published Oct 19, 2021 · Updated Aug 3, 2024

Cross-site request forgery in Snipe-IT before 5.3.0 allows remote attackers to restore deleted records through an authenticated user’s browser. Restore routes for manufacturers, assets, asset models, and users accept state-changing GET requests, so cross-origin navigation invokes them without a CSRF token. Exploitation requires an authenticated user with restore permission to load attacker-controlled content; the bounded consequence is unauthorized restoration of deleted inventory or account data.
