Reflected XSS via unescaped request parameters
Published Jan 16, 2024 · Updated Aug 30, 2024
Reflected XSS in ThimPress LearnPress before 4.2.5.5 allows remote attackers to run scripts in an administrator's browser. The instructors-page rendering path reflects attacker-controlled query-string markup into generated output without adequate sanitization or output escaping. Exploitation requires a high-privilege user, such as an administrator, to open a crafted URL; the injected script then runs in that user's browser context.
