{"id":"UBUNTU-CVE-2026-88056","details":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.30, 21.2.22, and 22.1.4, Angular Server-Side Rendering in @angular/platform-server processes user-controlled resource or request URLs through HttpClient after application code validates them with WHATWG URL parsing. The resolveUrl and parseUrl utilities called String.prototype.trim(), which removed leading Unicode whitespace such as U+00A0 or U+FEFF after the input passed a same-origin check, converting a relative path into a protocol-relative attacker-controlled URL. In affected applications that attach sensitive server-side credentials such as Authorization headers to approved requests, relativeUrlsTransformerInterceptorFn then dispatched the request to the attacker-controlled origin, causing SSRF and credential disclosure. This issue is fixed in versions 20.3.30, 21.2.22, and 22.1.4.","modified":"2026-09-16T14:03:24.947754984Z","published":"2026-09-10T19:17:00Z","upstream":["CVE-2026-88056"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-88056"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-88056"},{"type":"REPORT","url":"https://github.com/angular/angular/security/advisories/GHSA-f6mr-pjwc-34m4"}],"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/2026/UBUNTU-CVE-2026-88056.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/2026/UBUNTU-CVE-2026-88056.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-2026-88056.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-2026-88056.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-2026-88056.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_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-2026-88056.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
