{"id":"UBUNTU-CVE-2026-54265","details":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, an issue in the @angular/compiler package allows bypassing DOM property sanitization through the use of two-way property bindings. Specifically, when a native DOM property that requires sanitization (such as innerHTML, srcdoc, src, href, data, or sandbox) is bound using the two-way binding syntax (e.g., [(innerHTML)]=\"value\" or bindon-innerHTML=\"value\"), the Angular template compiler failed to apply the appropriate schema-derived sanitizer resolution to the TwoWayProperty operation. As a result, native two-way DOM bindings were emitted without the required sanitizer function, whereas equivalent one-way bindings would be properly sanitized. This flaw enables an attacker who can control the value of a two-way bound sensitive property to bypass Angular's built-in sanitization logic, potentially leading to client-side Cross-Site Scripting (XSS). This vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25.","modified":"2026-06-29T13:50:41.974379877Z","published":"2026-06-22T16:16:00Z","upstream":["CVE-2026-54265"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-54265"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-54265"}],"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_version":"1.2.28-1ubuntu2+esm1","binary_name":"libjs-angularjs"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54265.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_name":"libjs-angularjs","binary_version":"1.5.10-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54265.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_name":"libjs-angularjs","binary_version":"1.7.9-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54265.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/2026/UBUNTU-CVE-2026-54265.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/2026/UBUNTU-CVE-2026-54265.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/2026/UBUNTU-CVE-2026-54265.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/2026/UBUNTU-CVE-2026-54265.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
