Detailsinfo

A vulnerability was found in wpxpo WowStore Plugin up to 4.4.24. It has been declared as problematic. This vulnerability affects the function render_callback of the component Block Attribute. The manipulation of the argument filterMobileText with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. CVE summarizes:

The WowStore – Store Builder & Product Blocks for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'filterMobileText' Block Attribute in all versions up to, and including, 4.4.24 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The save-time wp_kses_post sanitization is ineffective because the payload is stored inside a Gutenberg block delimiter comment as JSON, which wp_kses_post preserves, allowing an attribute-breakout string to survive to the server-side render_callback.

The advisory is available at wordfence.com. This vulnerability was named CVE-2026-17161 since 07/24/2026. The exploitation appears to be easy. The attack can be initiated remotely. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059.007 by the MITRE ATT&CK project.
