CVE-2026-102778

Published Oct 5, 2026 Modified Oct 5, 2026 CWE-352 CWE-601

Description

Joomla Extension - svenbluege.de - Cross-site scripting and open redirect on the share mini page in Event Gallery extension < 6.6.0 - The page a shared image link opens (the share mini page of the front end) can link the article the image was shared from when the option "Share article links" is on. It took the address of the article from the shared link and printed it into the page without checking or escaping it; with the link type "Image Page with Redirect" it followed the address at once. A prepared link could therefore run a script in the page, in the session of the visitor who opened it, or send the visitor to another web site. Nothing on the server is changed or read by the server.
