CVE-2026-102776 · Severity: info · Published 2026-10-05

Event Gallery is a Joomla gallery component with e-commerce functionality that allows administrators to manage images, galleries, and store settings. The extension fails to validate request tokens on eight backend administrative tasks, allowing an attacker to craft a malicious webpage that—when visited by a logged-in administrator—silently changes settings like payment methods, shipping methods, watermarks, and event shop status. While no data can be deleted or read and orders are not affected, the vulnerability could lead to configuration tampering that disrupts the website's operation.

## Technical details

This is a cross-site request forgery (CSRF) vulnerability in the Event Gallery Joomla extension where multiple administrative backend actions lack form token validation. An unauthenticated attacker can host a malicious webpage that crafts requests to change payment/shipping methods, image watermarks, event shop status, main image selection, and image sorting—relying on an authenticated administrator's browser session to execute the actions. The vulnerability requires the target administrator to be logged in and visit the attacker's page, but no additional user interaction is needed once there.
