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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-101895)\n\nAffected packages:\n\n- `@angular/platform-server >= 22.0.0, < 22.1.6`\n- `@angular/platform-server >= 21.0.0, < 21.2.23`\n- `@angular/platform-server >= 20.0.0, < 20.3.31`\n- `@angular/platform-server <= 19.2.25`\n\nPatched in:\n\n- `@angular/platform-server 22.1.6`\n- `@angular/platform-server 21.2.23`\n- `@angular/platform-server 20.3.31`\n\nSource: https://github.com/advisories/GHSA-f67j-2jqw-jpq7","depth":"midnight","depthScore":60,"depthScoreParts":{"impact":47.8,"likelihood":0.2,"exploitation":12,"ransomware":0},"changes":[{"seq":221433,"id":"CVE-2026-101895","ts":1792031236616,"field":"exploit_available","old":"false","new":"true"},{"seq":221432,"id":"CVE-2026-101895","ts":1792031236616,"field":"cvss","old":null,"new":"8.7"}]}
