The vulnerability CVE-2024-44059 affects the Custom Query Blocks plugin by Ronald Huereca, specifically in the post-type-archive-mapping component. It is a DOM-based cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. The issue affects all versions up to and including 5.3.1. The CVSS v3.1 score is 6.5, indicating a medium severity with network attack vector, low attack complexity, requiring low privileges and user interaction, and impacts on confidentiality, integrity, and availability at a low level. No patch or official vendor advisory is currently available.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to limited disclosure of information, modification of data, or disruption of service. The attack requires user interaction and low privileges, limiting the scope but still posing a risk to affected installations.
