Insufficient Verification of Data Authenticity

Overview simplesamlphp/simplesamlphp is a PHP implementation of a SAML 2.0 service provider and identity provider, also compatible with Shibboleth 1.3 and 2.0. Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the processing of SAML responses wh...

SimpleSAMLphp SP accepts a response from an unexpected IdP when unsigned `Response/InResponseTo` is combined with a signed assertion lacking `SubjectConfirmationData/InResponseTo`

Summary SimpleSAMLphp's SAML SP ACS path does not enforce the IdP selected for an SP-initiated login. If a saved SP state contains ExpectedIssuer = IdP A, but the ACS receives a valid response from IdP B, the code logs a warning and continues processing instead of rejecting the response. That...
