{"id":"DEBIAN-CVE-2026-4645","details":"A flaw was found in the `github.com/antchfx/xpath` component. A remote attacker could exploit this vulnerability by submitting crafted Boolean XPath expressions that evaluate to true. This can cause an infinite loop in the `logicalQuery.Select` function, leading to 100% CPU utilization and a Denial of Service (DoS) condition for the affected system.","modified":"2026-03-30T19:02:45.160791Z","published":"2026-03-23T14:16:36.063Z","withdrawn":"2026-03-30T19:02:45.160791Z","upstream":["CVE-2026-4645"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-4645"}],"affected":[{"package":{"name":"golang-github-antchfx-xpath","ecosystem":"Debian:11","purl":"pkg:deb/debian/golang-github-antchfx-xpath?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.2-2","1.3.0-1","1.3.1-1","1.3.2-1","1.3.3-1","1.3.5-1","1.3.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-4645.json"}},{"package":{"name":"golang-github-antchfx-xpath","ecosystem":"Debian:12","purl":"pkg:deb/debian/golang-github-antchfx-xpath?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.2-2","1.3.0-1","1.3.1-1","1.3.2-1","1.3.3-1","1.3.5-1","1.3.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-4645.json"}},{"package":{"name":"golang-github-antchfx-xpath","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-github-antchfx-xpath?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.3-1","1.3.5-1","1.3.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-4645.json"}},{"package":{"name":"golang-github-antchfx-xpath","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-github-antchfx-xpath?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.6-1"}]}],"versions":["1.3.3-1","1.3.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-4645.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
