{"id":"UBUNTU-CVE-2026-17495","details":"moment is a JavaScript date library for parsing, validating, manipulating, and formatting dates. In versions 2.29.2 through 2.30.1, a specially crafted non-string object passed to moment.locale() can bypass the locale-name path-traversal guard. The guard assumes the input is a string, so an object whose match() method satisfies the check while its toString() returns a traversal path reaches an internal require() call with attacker-controlled path segments. This is an incomplete fix for CVE-2022-24785 and primarily affects npm (server-side) users that pass user-provided input directly to moment.locale(). The issue is fixed in moment 2.31.0, and users should upgrade to 2.31.0 or later. As a workaround, validate that any user-supplied input is a string before passing it to moment.locale().","modified":"2026-09-16T14:01:37.234165560Z","published":"2026-09-15T06:16:00Z","upstream":["CVE-2026-17495"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-17495"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-17495"},{"type":"REPORT","url":"https://cna.openjsf.org/security-advisories.html"},{"type":"REPORT","url":"https://github.com/moment/moment/security/advisories/GHSA-4p3w-j4w9-5jqw"}],"affected":[{"package":{"name":"node-moment","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/node-moment?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.6+dfsg-1","2.11.0+ds-1","2.11.0+ds-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.11.0+ds-1ubuntu0.1~esm1","binary_name":"libjs-moment"},{"binary_name":"node-moment","binary_version":"2.11.0+ds-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"node-moment","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-moment?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.18.1+ds-1","2.19.1+ds-1","2.19.2+ds-1","2.19.3+ds-1","2.19.4+ds-1","2.20.1+ds-1","2.20.1+ds-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-moment","binary_version":"2.20.1+ds-1ubuntu0.1"},{"binary_version":"2.20.1+ds-1ubuntu0.1","binary_name":"node-moment"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"node-moment","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-moment?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.24.0+ds-1","2.24.0+ds-2","2.24.0+ds-2ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-moment","binary_version":"2.24.0+ds-2ubuntu0.1"},{"binary_version":"2.24.0+ds-2ubuntu0.1","binary_name":"node-moment"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"node-moment","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-moment?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.29.1+ds-2","2.29.1+ds-3","2.29.1+ds-3ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-moment","binary_version":"2.29.1+ds-3ubuntu0.2"},{"binary_name":"node-moment","binary_version":"2.29.1+ds-3ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"python-xstatic-moment","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/python-xstatic-moment?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.4.2-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.8.4.2-2","binary_name":"python3-xstatic-moment"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"node-moment","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-moment?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.29.4+ds-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.29.4+ds-1","binary_name":"libjs-moment"},{"binary_name":"node-moment","binary_version":"2.29.4+ds-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"python-xstatic-moment","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/python-xstatic-moment?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.4.2-3"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-xstatic-moment","binary_version":"2.8.4.2-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"node-moment","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-moment?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.29.4+ds-1","2.30.1+ds-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-moment","binary_version":"2.30.1+ds-1"},{"binary_version":"2.30.1+ds-1","binary_name":"node-moment"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-17495.json"}},{"package":{"name":"python-xstatic-moment","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/python-xstatic-moment?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","even
