CVE-2026-90905: Joomla Easy Store extension missing CSRF and access control

CVE-2026-90905 · Severity: info · Published 2026-09-23

The Easy Store eCommerce extension for Joomla contains a configuration update endpoint that lacks protection against cross-site request forgery (CSRF) attacks and administrative permission checks. An attacker could trick a site administrator into visiting a malicious website that silently changes the site's email sender address and display name, potentially enabling email spoofing or phishing attacks against site users.

Technical details

The vulnerable endpoint (administrator/index.php?option=com_easystore&task=appconfig.updateConfiguration) modifies core Joomla configuration parameters (fromname, mailfrom) in configuration.php without validating CSRF tokens or verifying administrative privileges. An unauthenticated attacker can craft a forged POST/request that, when accessed by an authenticated admin, executes the malicious configuration update. The fix requires enforcing Session::checkToken() validation and explicit AccessControl::create()->canAdmin() authorization checks.
