The WP VR – 360 Panorama and Free Virtual Tour Builder For WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘hotspot-hover’ parameter in all versions up to, and including, 8.5.32 due to insufficient input sanitization and output escaping. 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.
