The HUSKY – Products Filter Professional for WooCommerce plugin suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, user-supplied shortcode attributes are not properly sanitized or escaped before being rendered, allowing authenticated users with contributor-level permissions or higher to inject arbitrary JavaScript code. This code executes in the context of any user who views the injected page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to and including 1.3.5.3. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required (low), no user interaction, and partial impact on confidentiality and integrity. There is no indication of an official patch or vendor advisory at this time.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via shortcode attributes. These scripts execute in the browsers of users who visit the infected pages, potentially compromising user sessions or performing unauthorized actions within the context of the affected site. The impact is limited to confidentiality and integrity with no direct availability impact. No known exploits are reported in the wild.

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 removing or disabling the vulnerable plugin if possible. Monitor for updates from the vendor or security community regarding patches or workarounds.
