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.","state":0,"publishedAt":"2026-09-10T19:17:41.477+00:00","modifiedAt":"2026-09-29T19:02:56.377+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.6,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/angular/angular/commit/3e924cc8dbbb57f23b262cb8f0d7e2bd0673034c","https://github.com/angular/angular/commit/5aa6d97deb9ef1de14e23748b7fa74f97d183132","https://github.com/angular/angular/commit/71e52d1396b9cef98652929b73e08c4cde645970","https://github.com/angular/angular/releases/tag/v20.3.30","https://github.com/angular/angular/releases/tag/v21.2.22","https://github.com/angular/angular/releases/tag/v22.1.4","https://github.com/angular/angular/security/advisories/GHSA-f6mr-pjwc-34m4"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-88056","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-918"],"productCriteria":["cpe:2.3:a:angular:angular:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-09-10T19:17:41.477","lastModified":"2026-09-29T19:02:56.377"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
