The Themify – WooCommerce Product Filter plugin (versions up to 1.5.1) suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows an attacker with high privileges and user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability. The CVSS 3.1 vector is AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L, reflecting network attack vector, low attack complexity, high privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker with high privileges to execute arbitrary scripts in the context of affected users, potentially leading to partial confidentiality, integrity, and availability impacts. The vulnerability is rated medium severity with a CVSS score of 5.9. There are no reports of active exploitation in the wild.
