{"cve":"CVE-2025-29774","nvd":{"published":"2025-03-14T17:15:52.870","modified":"2026-06-17T09:05:38.920","status":"Deferred","description":"xml-crypto is an XML digital signature and encryption library for Node.js. An attacker may be able to exploit a vulnerability in versions prior to 6.0.1, 3.2.1, and 2.1.6 to bypass authentication or authorization mechanisms in systems that rely on xml-crypto for verifying signed XML documents. The vulnerability allows an attacker to modify a valid signed XML message in a way that still passes signature verification checks. For example, it could be used to alter critical identity or access control attributes, enabling an attacker with a valid account to escalate privileges or impersonate another user. Users of versions 6.0.0 and prior should upgrade to version 6.0.1 to receive a fix. Those who are still using v2.x or v3.x should upgrade to patched versions 2.1.6 or 3.2.1, respectively.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":null,"cwes":["CWE-347"],"references":["https://github.com/node-saml/xml-crypto/commit/28f92218ecbb8dcbd238afa4efbbd50302aa9aed","https://github.com/node-saml/xml-crypto/commit/886dc63a8b4bb5ae1db9f41c7854b171eb83aa98","https://github.com/node-saml/xml-crypto/commit/8ac6118ee7978b46aa56b82cbcaa5fca58c93a07","https://github.com/node-saml/xml-crypto/releases/tag/v2.1.6","https://github.com/node-saml/xml-crypto/releases/tag/v3.2.1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:00:17.429720821+00:00"},"epss":{"cve":"CVE-2025-29774","score":0.09103,"percentile":0.95304,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9p8x-f768-wp2g","url":"https://osv.dev/vulnerability/GHSA-9p8x-f768-wp2g","summary":"xml-crypto Vulnerable to XML Signature Verification Bypass via Multiple SignedInfo References","modified":"2026-09-10T03:49:48.483681113Z","packages":[{"ecosystem":"npm","name":"xml-crypto","purl":"pkg:npm/xml-crypto","ranges":[">=4.0.0 <6.0.1"],"fixed":["6.0.1"]},{"ecosystem":"npm","name":"xml-crypto","purl":"pkg:npm/xml-crypto","ranges":[">=3.0.0 <3.2.1"],"fixed":["3.2.1"]},{"ecosystem":"npm","name":"xml-crypto","purl":"pkg:npm/xml-crypto","ranges":["<2.1.6"],"fixed":["2.1.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
