CVE-2026-101895
Published:September 28, 2026
Updated:September 30, 2026
A Denial of Service (DoS) vulnerability exists in "@angular/platform-server"'s DOM emulation parser ("domino"). When processing untrusted user input containing an incomplete DOCTYPE declaration ending with whitespace before EOF (such as "<!DOCTYPE html "), the HTML parser enters an infinite synchronous loop, pegging CPU utilization at 100% and completely freezing the Node.js server process.
