Stored XSS via unneutralized picture path
Published Apr 14, 2023 · Updated Aug 2, 2024
Cross-site scripting in EyouCMS 1.5.4 allows remote authenticated users to execute script in an administrator's browser. The Arctype edit handler stores the litpic_local form value as the New Picture image and later renders it without neutralizing HTML event-handler input. An authenticated backend session is required to submit the payload, and another administrator must reopen the edited item, enabling script execution in that browser.
