Safety vulnerability ID: 37783
The information on this page was manually curated by our Cybersecurity Intelligence Team.
PySAML2 before 5.0.0 does not check that the signature in a SAML document is enveloped and thus signature wrapping is effective, i.e., it is affected by XML Signature Wrapping (XSW). The signature information and the node/object that is signed can be in different places and thus the signature verification will succeed, but the wrong data will be used. This specifically affects the verification of assertion that have been signed.
Latest version: 7.5.0
Python implementation of SAML Version 2 Standard
