The hookandhook Post Grid Elementor Addon contains an improper input neutralization vulnerability leading to cross-site scripting (XSS). This affects versions up to 2.0.18 and allows an attacker with low privileges to inject malicious scripts that execute in the context of other users, contingent on user interaction. The CVSS 3.1 base score is 6.5, indicating a medium severity with impacts on confidentiality, integrity, and availability. No patch or official fix details have been provided, and the product is not a cloud service.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to partial confidentiality, integrity, and availability impacts. The attack requires user interaction and low privileges, limiting the ease of exploitation. There are no reports of active exploitation in the wild.
