CVE-2026-32246
Tinyauth vulnerable to TOTP/2FA bypass via OIDC authorize endpoint
Summary
Tinyauth vulnerable to TOTP/2FA bypass via OIDC authorize endpoint
Original description
The description as published by the source.
Tinyauth is an authentication and authorization server. Prior to 5.0.3, the OIDC authorization endpoint allows users with a TOTP-pending session (password verified, TOTP not yet completed) to obtain authorization codes. An attacker who knows a user's password but not their TOTP secret can obtain valid OIDC tokens, completely bypassing the second factor. This vulnerability is fixed in 5.0.3.
