Name of the Vulnerable Software and Affected Versions Leaflet Map plugin for WordPress versions up to, and including, 3.3.0

Description The issue is related to Stored Cross-Site Scripting via shortcodes due to insufficient input sanitization and output escaping. This allows authenticated attackers with contributor level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 3.3.0, update to a version higher than 3.3.0 to resolve the issue. As a temporary workaround, consider restricting the use of shortcodes to minimize the risk of exploitation.
