Reflected XSS via unescaped post-type labels
Published Mar 19, 2026 · Updated Mar 19, 2026
Reflected XSS in Website LLMs.txt 8.2.6 and earlier allows remote attackers to execute script in a victim's browser. The admin settings interface places dynamic custom-post-type labels into HTML form attributes without consistent escaping and uses labels as array keys. A victim must load the affected admin response; public sources do not identify the request parameter that provides the reflected input.
