CVE-2026-100747
Joomla Extension - svenbluege.de - CSRF in image upload in Event Gallery extension < 6.5.0 - Due to lack of an CSRF token check, a third-party site can upload files to an event and overwrite existing files with the same name.
Does this matter?
Lower severity and a low EPSS score (0.11%). Track it; it rarely justifies an emergency change on its own.
