CVE-2026-66582Known exploitationNetwork attack vector

Reflected XSS via gettext-marked search parameter

Published Aug 20, 2026 · Updated Aug 20, 2026

Reflected XSS in Cozmoslabs TranslatePress 3.3.2 and earlier allows remote attackers to execute scripts through a crafted search query. The Translation Editor processes gettext markers embedded in the search-query parameter without neutralizing script-capable input before browser output. No authentication is required, but a victim must interact with the affected output; scripts run in the site's origin and can read or alter browser-accessible data.
