Stored XSS via encoded gettext comment markers
Published Aug 6, 2026 · Updated Aug 6, 2026
Stored XSS in Cozmoslabs TranslatePress 3.2.6 and earlier allows remote attackers to inject scripts through crafted comment content. The translation renderer processes percent-encoded gettext markers that survive WordPress filtering, then incorporates insufficiently bounded matched text into rendered attributes without adequate escaping. No authentication is required; comment moderation can delay first-time submissions, but an accepted payload executes in a visitor's WordPress origin.
