The Element Pack Elementor Addons plugin for WordPress (CVE-2024-3926) contains a Stored Cross-Site Scripting vulnerability affecting all versions up to and including 5.6.1. The vulnerability was discovered in May 2024 and is related to insufficient input sanitization and output escaping of user-supplied attributes in the custom_attributes value in widgets (NVD).

The vulnerability stems from improper input sanitization and output escaping of the custom_attributes value in widgets. It has been assigned a CVSS v3.1 base score of 5.4 (Medium) by NVD with vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, while Wordfence assigned a score of 6.4 (Medium) with vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N (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 a user accesses the compromised page (NVD).

The vulnerability requires an authenticated user with at least contributor-level privileges to exploit. The attack vector is network-accessible (AV:N) with low attack complexity (AC:L) and requires low privileges (PR:L) (NVD).

Users should upgrade to a version newer than 5.6.1 which contains the security fix. A patch has been made available through the WordPress plugin repository (WordPress Patch).
