{"id":"CVE-2022-39300","summary":"Signature bypass via multiple root elements in node-SAML","details":"node SAML is a SAML 2.0 library based on the SAML implementation of passport-saml. 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 node-saml version 4.0.0-beta5 or newer. Disabling SAML authentication may be done as a workaround.","aliases":["GHSA-5p8w-2mvw-38pv"],"modified":"2026-07-15T01:49:04.806862203Z","published":"2022-10-13T00:00:00Z","database_specific":{"cwe_ids":["CWE-347"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39300.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39300.json"},{"type":"ADVISORY","url":"https://github.com/node-saml/node-saml/security/advisories/GHSA-5p8w-2mvw-38pv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39300"},{"type":"FIX","url":"https://github.com/node-saml/node-saml/commit/c1f275c289c01921e58f5c70ce0fdbc5287e5fbe"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/node-saml/node-saml","events":[{"introduced":"0"},{"fixed":"3618410143053521b7bcd9a9b8326bcc056691a5"},{"fixed":"c1f275c289c01921e58f5c70ce0fdbc5287e5fbe"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:node_saml_project:node_saml:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0"},{"fixed":"4.0.0"}]}}],"versions":["v4.0.0-beta.6","v4.0.0-beta.5","v4.0.0-beta.4","v4.0.0-beta.3","v4.0.0-beta.2","v3.0.0","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.5.0","v1.4.2","v1.4.1","v1.4.0","v1.3.5","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.0","v1.0.0","v0.35.0","v0.34.0","v0.33.0","v0.32.1","v0.32.0","v0.30.0","v0.20.2","v0.16.2","v0.16.1","v0.16.0","v0.15.0","v0.14.0","v0.13.0","v0.12.0","v0.11.1","v0.11.0","v0.10.0","v0.9.2","v0.9.1","v0.9.0","v0.8.0","v0.7.0","v0.6.2","v0.6.1","v0.6.0","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.0","v0.3.0","v0.2.1","v0.2.0","v0.1.0","0.0.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-39300.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:L"}]}
