  "title": "social-auth-core: Python Social Auth is a social authentication/registration mechanism",
  "description": "Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the SAML backend accepted SAML responses on the Assertion Consumer Service endpoint without verifying that they matched a previously issued \u0060AuthnRequest\u0060. Applications using SAML account association could allow an attacker with a valid account on a trusted IdP to link the attacker\u0027s SAML identity to a logged-in victim\u0027s local account. The attacker could then authenticate through SAML and gain access to the victim\u0027s account. The issue affects applications using the SAML backend together with authenticated account association. The issue has been fixed in version 5.0.0 by validating SAML responses against stored \u0060AuthnRequest\u0060 IDs.",
