Executive brief
The WowStore plugin for WordPress, which provides tools for building WooCommerce online stores, contains a security flaw that allows users with contributor-level access or higher to inject malicious scripts into website pages. These scripts will automatically run in the browser of any visitor who views the affected page. This could lead to unauthorized actions being performed on behalf of site visitors or administrators, potentially compromising user sessions or site integrity.
Technical details
The WowStore plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'currentPostId' block attribute. Authenticated attackers with contributor-level permissions or higher can exploit this by injecting arbitrary web scripts into a page via the block editor. Because the input is stored and later rendered without proper security filtering, the script executes in the context of any user's browser who visits the compromised page. The vulnerability is present in all versions up to and including 4.4.24. A patch has been identified in recent changesets to address the improper neutralization of input.
