+  <background>
+    <p>PySAML2 is a pure python implementation of SAML2</p>

+  <description>
+    <p>It was found that the PySAML2 relies on an assert statement to check the
+      user’s password. A python optimizations might remove this assertion.
+    </p>

+  <impact type="normal">
+    <p>A remote attacker could bypass security restrictions and access any
+      application which is using PySAML2 for authentication.
