MEDIUM6.1EPSS 0.04%Authlib OIDC Implicit/Hybrid Authorization Vulnerable to Open Redirect
發布日:2026/5/13修改日:2026/5/29
描述
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.
