What the vulnerability does
01Description
The WP Go Maps (formerly WP Google Maps) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘wpgmza_custom_js’ parameter in all versions up to, and including, 10.0.05 due to insufficient input sanitization and output escaping and missing capability check in the 'admin_post_wpgmza_save_settings' hook anonymous function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
02Summary
WP Go Maps versions 10.0.05 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other site visitors. The vulnerability has a changed scope, meaning the impact extends beyond the plugin itself to other components or users. Site administrators should update to a version newer than 10.0.05 to mitigate this risk.
