Prior to 20.3.30, 21.2.22, and 22.1.4, Angular server-side rendering (SSR) in @angular/platform-server serializes ProcessingInstruction DOM nodes inside fallback raw-content elements without escaping matching ancestor closing tags. ProcessingInstruction data escaped greater-than characters but left less-than characters untouched and did not inspect fallback ancestors, so data such as a matching closing tag prematurely terminates noscript, iframe, noembed, or noframes containers. The vulnerable nodes cannot be authored through standard Angular templates; reachability requires application or library code using inject(DOCUMENT).createProcessingInstruction with attacker-controlled data or Renderer2 DOM insertion inside a fallback container. In HTML5 RAWTEXT parsing, the premature close causes subsequent sibling elements to be interpreted as live HTML and enables arbitrary JavaScript execution in a victim's browser. This issue is fixed in versions 20.3.30, 21.2.22, and 22.1.4."}], "lastModified": "2026-09-29T19:01:24.747", "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"}
