CVE-2024-11199: 
WordPress vulnerability analysis and mitigation

The Rescue Shortcodes plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2024-11199) in versions up to and including 2.9. The vulnerability exists in the plugin's rescue_progressbar shortcode due to insufficient input sanitization and output escaping on user-supplied attributes (NVD).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) with a CVSS v3.1 base score of 6.4 MEDIUM (Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). The issue stems from inadequate sanitization of user input in the rescue_progressbar shortcode functionality (NVD, Wordfence).

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 (NVD).

The vulnerability requires an authenticated user with at least contributor-level privileges to exploit. The attack complexity is considered low, requiring no special conditions or circumstances for exploitation (NVD).

Users should update to a version newer than 2.9 if available. The vulnerability was addressed in recent updates that improved input sanitization and output escaping (WordPress Plugin).
