Bytebase 0.12.0 before 1.0.1 Authentication Bypass via GitLab Self-Hosted Login

Impact

Bytebase versions 0.12.0 before 1.0.1 have an authentication bypass vulnerability via GitLab self-hosted login, allowing unauthenticated attackers to log in as any user. The flaw stems from trusting client-supplied GitLab provider configuration. Attackers can impersonate existing users, including the Owner, or create new members.

Original source description

Bytebase 0.12.0 before 1.0.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as any user. The flaw stems from trusting client-supplied GitLab provider configuration in the POST /api/auth/login/GITLAB_SELF_HOST endpoint. Attackers can set instanceUrl to a server they control that returns an active user with a chosen email. Bytebase then issues session tokens for that principal, letting attackers impersonate existing users including the Owner or create new members.
