CVE-2026-111641 Details
Description
FastapiAdmin through 3.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to obtain sessions for any user by abusing unprotected auto-login endpoints. Attackers can list users via /api/v1/auth/auto-login/users, mint a superuser auto-login token, and exchange it for a JWT session to gain full administrative control.
A critical authentication bypass vulnerability has been identified in FastapiAdmin versions through 3.0. This vulnerability allows unauthenticated attackers to gain access to user sessions by exploiting unprotected auto-login endpoints. Attackers can enumerate users via the '/api/v1/auth/auto-login/users' endpoint, generate a superuser auto-login token, and exchange it for a JWT session, thereby obtaining full administrative privileges.
To address this vulnerability, add authentication dependencies to the auto-login routes, ensuring that only authenticated administrators can access them. Additionally, remove the default hard-coded JWT signing secret and require operators to set it explicitly in their environment.
