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.","state":0,"publishedAt":"2026-09-10T19:17:41.8+00:00","modifiedAt":"2026-09-29T19:01:24.747+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:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/angular/angular/commit/73d8bbd27cb46495426d4132975a1355b47ad915","https://github.com/angular/angular/commit/89b20568dfaee1ec8e0b3bcf1872acdddd2f4fef","https://github.com/angular/angular/commit/ba3bc47b20b3d12f5eb141ec9c651373ae4d15e8","https://github.com/angular/angular/issues/70146","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-j3r3-mxqp-r2p4","https://github.com/angular/domino/commit/04f987dc08ff3736b427f50941adf1722458528f"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-88058","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-79","CWE-116"],"productCriteria":["cpe:2.3:a:angular:angular:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-09-10T19:17:41.800","lastModified":"2026-09-29T19:01:24.747"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
