This vulnerability (CVE-2024-39644) in Modernaweb Studio's Black Widgets For Elementor plugin allows stored Cross-site Scripting (CWE-79) due to improper input neutralization during web page generation. It affects versions up to 1.3.5 and can lead to script execution in the context of users viewing the compromised content. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of users visiting affected web pages, potentially leading to session hijacking, defacement, or other malicious actions impacting confidentiality, integrity, and availability at a low level. The medium CVSS score reflects these impacts but also the requirement for some privileges and user interaction.

No official patch or remediation guidance is currently available from the vendor. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
