WordPress vulnerability analysis and mitigation

The Map Block Leaflet plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability (CVE-2025-5122) in versions up to and including 3.2.1. The vulnerability was discovered in the 'url' parameter due to insufficient input sanitization and output escaping. The issue was publicly disclosed on May 28, 2025, and affects WordPress installations using the Map Block Leaflet plugin (NVD, Wiz).

The vulnerability stems from improper sanitization of the 'url' parameter in the plugin's functionality. It has been assigned a CVSS v3.1 base score of 6.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79: Improper Neutralization of Input During Web Page Generation (NVD, Wordfence).

When exploited, this vulnerability allows authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts are executed whenever users access the affected pages, potentially leading to unauthorized actions depending on the user's privileges (NVD).

The vulnerability has been patched in version 3.2.2 of the Map Block Leaflet plugin. The fix includes proper URL escaping using esc_url for map and marker images. Users are advised to update to version 3.2.2 or later immediately (WordPress Plugin).
