The PowerPack Addons for Elementor plugin for WordPress (CVE-2024-2491) contains a Stored Cross-Site Scripting vulnerability discovered in versions up to and including 2.7.17. The vulnerability was publicly disclosed on March 29, 2024, and affects the _html_tag attribute of multiple widgets in the plugin (NVD, WPScan).

The vulnerability stems from insufficient input sanitization and output escaping in the _html_tag attribute of multiple widgets. It has been assigned a CVSS v3.1 base score of 6.4 (Medium) by Wordfence and 5.4 (Medium) by NIST, with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79: Improper Neutralization of Input During Web Page Generation (NVD).

When exploited, this vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever any user accesses the compromised page, potentially leading to data theft, session hijacking, or other malicious actions (NVD, WPScan).

The vulnerability requires an authenticated user with at least contributor-level access to exploit. The attack complexity is considered low, requiring network access and user interaction for successful exploitation, as indicated by the CVSS metrics (NVD).
