{"id":"UBUNTU-CVE-2025-66412","details":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 21.0.2, 20.3.15, and 19.2.17, A Stored Cross-Site Scripting (XSS) vulnerability has been identified in the Angular Template Compiler. It occurs because the compiler's internal security schema is incomplete, allowing attackers to bypass Angular's built-in security sanitization. Specifically, the schema fails to classify certain URL-holding attributes (e.g., those that could contain javascript: URLs) as requiring strict URL security, enabling the injection of malicious scripts. This vulnerability is fixed in 21.0.2, 20.3.15, and 19.2.17.","modified":"2026-05-20T16:23:41.373291948Z","published":"2025-12-01T23:15:00Z","upstream":["CVE-2025-66412"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-66412"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-66412"},{"type":"REPORT","url":"https://github.com/angular/angular/security/advisories/GHSA-v4hv-rgfq-gp49"},{"type":"REPORT","url":"https://github.com/angular/angular/commit/1c6b0704fb63d051fab8acff84d076abfbc4893a"}],"affected":[{"package":{"name":"angular.js","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/angular.js?arch=source&distro=esm-infra%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.28-1ubuntu2","1.2.28-1ubuntu2+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-angularjs","binary_version":"1.2.28-1ubuntu2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66412.json"}},{"package":{"name":"angular.js","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/angular.js?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5.10-1","1.5.10-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.5.10-1ubuntu0.1~esm1","binary_name":"libjs-angularjs"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66412.json"}},{"package":{"name":"angular.js","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/angular.js?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5.10-1","1.7.9-1","1.7.9-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.7.9-1ubuntu0.1~esm1","binary_name":"libjs-angularjs"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66412.json"}},{"package":{"name":"angular.js","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/angular.js?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.2-2","1.8.2-2ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-angularjs","binary_version":"1.8.2-2ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66412.json"}},{"package":{"name":"angular.js","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/angular.js?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.3-1","1.8.3-1ubuntu0.24.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-angularjs","binary_version":"1.8.3-1ubuntu0.24.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66412.json"}},{"package":{"name":"angular.js","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/angular.js?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.3-1","1.8.3-3"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-angularjs","binary_version":"1.8.3-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66412.json"}},{"package":{"name":"angular.js","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/angular.js?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.3-3"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.3-3","binary_name":"libjs-angularjs"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66412.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
