CVE-2025-27773
GHSA-46r4-f8gj-xg56
The SimpleSAMLphp SAML2 library incorrectly verifies signatures for HTTP-Redirect binding There's a signature confusion attack in the HTTPRedirect binding. An attacker with any signed SAMLResponse via the HTTP-Redirect binding can cause the application to accept an unsigned message. I believe that it exists for v4 only. I have not yet developed a PoC. V5 is well designed and instead builds the signed query from the same message that will be consumed.
