Name of the Vulnerable Software and Affected Versions: Geo Mashup plugin for WordPress versions up to, and including, 1.13.13

Description: The issue is related to Stored Cross-Site Scripting in the Geo Mashup plugin for WordPress. It occurs due to insufficient input sanitization and output escaping on user-supplied attributes in the geo mashup visible posts list shortcode. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 1.13.13, 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 geo mashup visible posts list shortcode to minimize the risk of exploitation.
