{"id":"CVE-2022-39299","aliases":["GHSA-m974-647v-whv7"],"url":"https://o3.security/vulnerability/CVE-2022-39299","summary":"Signature bypass via multiple root elements in Passport-SAML","details":"Passport-SAML is a SAML 2.0 authentication provider for Passport, the Node.js authentication library. A remote attacker may be able to bypass SAML authentication on a website using passport-saml. 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 generation of a signed message can be triggered. Users should upgrade to passport-saml version 3.2.2 or newer. The issue was also present in the beta releases of `node-saml` before version 4.0.0-beta.5. If you cannot upgrade, disabling SAML authentication may be done as a workaround.","published":"2022-10-12T00:00:00Z","modified":"2026-08-12T03:51:34.693605709Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":{"score":0.03381,"percentile":0.87883,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":2,"affectedPackages":[{"ecosystem":"npm","name":"passport-saml","fixedVersion":"3.2.2"},{"ecosystem":"npm","name":"node-saml","fixedVersion":"4.0.0-beta.5"},{"ecosystem":"npm","name":"@node-saml/node-saml","fixedVersion":"4.0.0-beta.5"},{"ecosystem":"npm","name":"@node-saml/passport-saml","fixedVersion":"4.0.0-beta.3"}],"fix":{"url":"https://github.com/node-saml/passport-saml/commit/8b7e3f5a91c8e5ac7e890a0c90bc7491ce33155e","label":"node-saml/passport-saml@8b7e3f5"},"references":[{"type":"WEB","url":"http://packetstormsecurity.com/files/169826/Node-saml-Root-Element-Signature-Bypass.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39299.json"},{"type":"ADVISORY","url":"https://github.com/node-saml/passport-saml/security/advisories/GHSA-m974-647v-whv7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39299"},{"type":"FIX","url":"https://github.com/node-saml/passport-saml/commit/8b7e3f5a91c8e5ac7e890a0c90bc7491ce33155e"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:34.693605709Z"}}
