The lack of checking of current timestamp allows a LogoutRequest XML to be reused multiple times even when the current time is past the NotOnOrAfter. This could impact the user where they would be logged out from an expired LogoutRequest. In bigger contexts, if LogoutRequests are sent out in mass to different SPs, this could impact many users on a large scale. This issue was patched in version 4.0.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-613","CWE-347"],"references":["https://github.com/node-saml/node-saml/commit/045e3b9c54211fdb95f96edf363679845b195cec","https://github.com/node-saml/node-saml/releases/tag/v4.0.5","https://github.com/node-saml/node-saml/security/advisories/GHSA-vx8m-6fhw-pccw","https://github.com/node-saml/node-saml/commit/045e3b9c54211fdb95f96edf363679845b195cec","https://github.com/node-saml/node-saml/releases/tag/v4.0.5"],"products":["node_saml_project:node_saml"],"source":"nvd","synced_at":"2026-10-19T21:39:14.809778102+00:00"},"epss":{"cve":"CVE-2023-40178","score":0.00491,"percentile":0.42243,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vx8m-6fhw-pccw","url":"https://osv.dev/vulnerability/GHSA-vx8m-6fhw-pccw","summary":"@node-saml/node-saml's validatePostRequestAsync does not include checkTimestampsValidityError","modified":"2026-09-10T03:49:57.758207788Z","packages":[{"ecosystem":"npm","name":"@node-saml/node-saml","purl":"pkg:npm/%40node-saml/node-saml","ranges":["<4.0.5"],"fixed":["4.0.5"]}]}],"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).
