The Dynamic AJAX Product Filters for WooCommerce plugin suffers from a stored XSS vulnerability (CWE-79) via the ‘name’ parameter. This occurs because the plugin fails to properly neutralize input before including it in web pages, allowing authenticated users with Contributor or higher privileges to inject arbitrary JavaScript. The injected scripts execute in the context of users viewing the affected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 1.3.7. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and partial confidentiality and integrity impact without availability impact. No patch or vendor advisory is currently provided.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the ‘name’ parameter, which execute in the browsers of users who view those pages. This can lead to partial compromise of confidentiality and integrity of user data within the affected WordPress environment. There is no known impact on availability. No known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the affected plugin. Monitor official sources for updates or patches from plugincy.
