Description

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.
