PYSEC-2021-48
Record from OSV · Published January 21, 2021
pysaml2 is fixed in 6.5.0 and 1d8fd268f5bf887480a403a7a5ef8f048157cc14 (PyPI)
PySAML2 is a pure python implementation of SAML Version 2 Standard. PySAML2 before 6.5.0 has an improper verification of cryptographic signature vulnerability. All users of pysaml2 that need to validate signed SAML documents are impacted. The vulnerability is a variant of XML Signature wrapping because it did not validate the SAML document against an XML schema. This allowed invalid XML documents to be processed and such a document can trick pysaml2 with a wrapped signature. This is fixed in PySAML2 6.5.0.
