Description

Joomla Extension - joomshaper.com - Missing CSRF and Access Control on Site Configuration Update in Easy Store extension 1.0.0-3.0.0 - The endpoint administrator/index.php?option=com_easystore&task=appconfig.updateConfiguration updated core Joomla mail configuration (fromname, mailfrom) in configuration.php without verifying anti-CSRF tokens or checking for administrative permissions (canAdmin). A malicious site could silently modify the site's sender name and email address via forged requests from an admin's browser. Resolved by enforcing Session::checkToken('request') / Session::checkToken('post') and adding explicit administrative authorization verification via AccessControl::create()->canAdmin().
