Unauthorized item exposure and modification via inconsistent checks

Published Jul 22, 2026 · Updated Jul 22, 2026

Administrator actions, editor popups, and import/export handlers fail to consistently enforce CSRF tokens, item permissions, and input validation. Exploitation requires unauthorized Joomla backend access or an authenticated administrator induced to submit a forged request, and permits exposure, creation, or modification of extension items and configuration.
