The WPCafe – Online Food Ordering, Restaurant Menu, Delivery, and Reservations for WooCommerce WordPress plugin suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the Reservation Form shortcode does not adequately sanitize or escape user-supplied attributes, enabling authenticated attackers with contributor-level privileges or above to inject arbitrary JavaScript code. This code executes in the context of users visiting the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 2.2.24.

An attacker with contributor-level or higher access can inject malicious scripts that execute in the browsers of users who view the affected pages. This can lead to theft of user credentials, session tokens, or other sensitive information accessible via the browser context. The vulnerability does not impact availability but compromises confidentiality and integrity of user sessions and data within the affected WordPress environment.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Reservation Form shortcode. Monitor vendor channels for updates and apply patches promptly once released.
