Name of the Vulnerable Software and Affected Versions MapPress Maps for WordPress versions up to, and including, 2.88.4

Description The issue is related to Stored Cross-Site Scripting via the mappress shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. 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, 2.88.4, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the mappress shortcode for users with contributor-level and above permissions until a patch is available.
