CVE-2026-4389
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.
