smart-sso through 2.1.1 OAuth2 Authorization Code Theft via Unvalidated redirectUri
smart-sso through 2.1.1 contains an open redirect vulnerability in the /login handler that allows unauthenticated attackers to steal OAuth2 authorization codes by supplying an unvalidated redirectUri parameter. Attackers can send crafted /login links to users with active SSO sessions, then redeem stolen codes at /oauth2/access_token with any valid client credentials to obtain victims' access tokens.
