Snipe-IT 4.2.0 through 8.6.3 Permission Bypass via OAuth

Assigner: VulnCheck
Reserved: 08.09.2026 Published: 09.09.2026 Updated: 09.09.2026

Snipe-IT versions 4.2.0 through 8.6.3 expose Laravel Passport's auto-registered personal-access-token routes (GET, POST, DELETE /oauth/personal-access-tokens*) with only 'web' and 'auth:web' middleware, without the self.api permission gate that Snipe-IT enforces on its own token endpoints (/account/api and /api/v1/account/personal-access-tokens). Any user with a valid web session and the corresponding CSRF token can POST to /oauth/personal-access-tokens and mint a long-lived bearer token for their own account, even when an administrator has denied the self.api permission. The issued token is still subject to existing per-endpoint authorization policies, so this is not a privilege escalation; it defeats the administrative control intended to block API/scripted access at the user's own permission level. Fixed in 8.7.0 (commit 3f74b8c), which registers overriding routes wrapped in the can:self.api middleware.
