+  date: 2024-08-28
+  description: |
+    Ruby-SAML in <= 12.2 and 1.13.0 <= 1.16.0 does not properly verify the signature of the SAML Response.
+    An unauthenticated attacker with access to any signed saml document (by the IdP) can thus forge a SAML
+    Response/Assertion with arbitrary contents. This would allow the attacker to log in as arbitrary user within
+    the vulnerable system.
