CVE-2026-12970Public exploitNetwork attack vector

Script execution via unescaped c_search attribute

Published Jul 20, 2026 · Updated Jul 20, 2026

Reflected XSS in ThimPress LearnPress before 4.4.1 allows remote attackers to run script in an instructor's or administrator's browser. Course Builder question, quiz, and lesson search pages place c_search directly inside a value attribute without escaping, so quote-breaking input injects an autofocus event handler. Exploitation requires a logged-in user with Course Builder access to open a crafted link; the script then runs in the site's origin with that user's privileges.
