A vulnerability present starting in version 3.0.5 up to and including version 4.6.3 allows an attacker to impersonate any user during SAML authentication by crafting a SAMLResponse. This can be done by using a valid SAML object that was signed by the configured IdP. Users are affected specifically when the service provider is using passport-wsfed-saml2 and a valid SAML document signed by the Identity Provider can be obtained. Version 4.6.4 contains a fix for the vulnerability.","published":"2025-05-06T21:16:20.000Z","lastModified":"2026-06-17T09:26:39.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":9.3,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-287"],"affected":[],"epss":{"score":0.00423,"percentile":0.36374,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.42%).
