CVE-2026-55476
|
| Summary | Snipe-IT Vulnerable to Unauthorized Asset Request Cancellation via Unguarded cancel_by_admin Parameter ### Impact The route POST `/account/request/{itemType}/{itemId}/{cancel_by_admin?}/{requestingUser?}` accepts `cancel_by_admin` as a plain URL path segment with no authorization check. Any authenticated user regardless of permissions can set this parameter to a truthy value and supply a victim's user ID to silently cancel that user's pending asset requests. The attacker only needs an active session; no elevated privilege is required. ### Patches Patched in 8.6.1 |
