CVE-2026-111714

tarteaucitron.js before 1.37.0 contains a regular expression denial of service vulnerability that allows attackers to block visitor pages by supplying unescaped cookie names to cookie.purge. Attackers can plant a cookie from a sibling subdomain or inject a purgeBtn element with a catastrophic-backtracking data-cookie pattern that freezes the page when the purge button is clicked.
