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."}], "lastModified": "2026-09-29T19:02:56.377", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:angular:angular:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "E33A4BDD-13F2-4937-9328-488EB06169A7", "versionEndIncluding": "19.2.25", "versionStartIncluding": "19.0.0"}, {"criteria": "cpe:2.3:a:angular:angular:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "8AB46288-7919-451D-AE5F-97A7371F130A", "versionEndExcluding": "20.3.30", "versionStartIncluding": "20.0.0"}, {"criteria": "cpe:2.3:a:angular:angular:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "2EC4EC89-DAE6-4B7A-B27B-ED329454145F", "versionEndExcluding": "21.2.22", "versionStartIncluding": "21.0.0"}, {"criteria": "cpe:2.3:a:angular:angular:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "7A3D8CF6-1272-4004-8C88-373910CDEE48", "versionEndExcluding": "22.1.4", "versionStartIncluding": "22.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
