Details

Social-auth-core 4.7.0 before 7.0.0 contains a login cross-site request forgery vulnerability in the SAML backend that restores sessions named in the unsigned RelayState parameter. Attackers can deliver their own valid IdP response and RelayState to a victim's browser via an auto-submitting form, signing the victim into the attacker's account to capture entered data.
