Vulnerability Overview

The DSGVO snippet for Leaflet Map and its Extensions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `leafext-cookie-time` and `leafext-delete-cookie` shortcodes in all versions up to, and including, 3.1. This is due to insufficient input sanitization and output escaping on user supplied attributes (`unset`, `before`, `after`). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 3.4, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
