CWE-639 #nvd

Full technical detail▾

Overview

Peppermint through 0.5.5 contains an authorization bypass vulnerability in the GET /api/v1/auth/user/:id/logout endpoint that allows authenticated attackers to delete sessions for any user by supplying arbitrary user IDs. Attackers can forcibly log out any user including administrators by calling the logout handler with another user's ID, since the endpoint performs no authorization checks to verify the caller owns the target account.
