{"id":"CVE-2026-101895","published":"2026-10-14T15:17:03.370","lastModified":"2026-10-16T16:00:33.533","description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.31, 21.2.23, and 22.1.6, the @angular/platform-server DOM emulation parser can enter an infinite synchronous loop when Angular server-side rendering processes attacker-controlled HTML containing an incomplete DOCTYPE that ends with whitespace at end of input. In Domino lib/HTMLParser.js, after_doctype_name_state emits doctype and EOF tokens without advancing nextchar or leaving the fixed-lookahead state, so the scanner repeatedly handles the same EOF marker. A remote unauthenticated attacker can use this condition through server-side HTML parsing paths such as innerHTML binding to consume a Node.js SSR worker at full CPU, starve the event loop, and stop concurrent and subsequent requests. This issue is fixed in versions 20.3.31, 21.2.23, and 22.1.6.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-400","CWE-835"],"vendors":[],"products":[],"references":[{"url":"https://github.com/angular/angular/commit/3db26e2544964d07a520836ad01f02f36ec88e25","tags":[]},{"url":"https://github.com/angular/angular/commit/fc2e8fbc0bda2f5c11585e8a0cbd88c074f5e567","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v20.3.31","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v21.2.23","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v22.1.6","tags":[]},{"url":"https://github.com/angular/angular/security/advisories/GHSA-f67j-2jqw-jpq7","tags":[]},{"url":"https://github.com/angular/domino/commit/4d97473116d000e3fd4d6f75ec98cbd67576fa6f","tags":[]},{"url":"https://github.com/angular/angular/security/advisories/GHSA-f67j-2jqw-jpq7","tags":[]}],"exploitRefs":[{"url":"https://github.com/angular/angular/commit/3db26e2544964d07a520836ad01f02f36ec88e25","tags":[]},{"url":"https://github.com/angular/angular/commit/fc2e8fbc0bda2f5c11585e8a0cbd88c074f5e567","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v20.3.31","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v21.2.23","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v22.1.6","tags":[]},{"url":"https://github.com/angular/angular/security/advisories/GHSA-f67j-2jqw-jpq7","tags":[]},{"url":"https://github.com/angular/domino/commit/4d97473116d000e3fd4d6f75ec98cbd67576fa6f","tags":[]},{"url":"https://github.com/angular/angular/security/advisories/GHSA-f67j-2jqw-jpq7","tags":[]}],"hasPoc":true,"ai":null}
