Description
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.6.12 and 1.7.1, an unauthenticated open redirect in Authlib's OpenIDImplicitGrant and OpenIDHybridGrant authorization endpoint lets a remote attacker cause the authorization server to issue an HTTP 302 to an attacker-chosen URL by submitting an authorization request that omits the openid scope. This vulnerability is fixed in 1.6.12 and 1.7.1.
Problem types
CWE-601: URL Redirection to Untrusted Site ('Open Redirect')
CWE-863: Incorrect Authorization
Product status
>= 1.7.0, < 1.7.1
