Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Test your applicationsUpgrade passport-saml
to version 3.2.2 or higher.
passport-saml is an authentication provider for Passport, the Node.js authentication library.
Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature by allowing a remote attacker to bypass SAML authentication on a website using passport-saml
.
Note A successful attack requires that the attacker is in possession of an arbitrary IDP-signed XML element. Depending on the IDP used, fully unauthenticated attacks (e.g, without access to a valid user) might also be feasible if the generation of a signed message can be triggered.
Users who are unable to upgrade to the fixed version should disable SAML authentication.
