Name of the Vulnerable Software and Affected Versions Image Hover Effects Ultimate plugin for WordPress versions up to, and including, 9.7.3

Description The issue is related to Stored Cross-Site Scripting via the Media Image URL value that can be added to an Image Hover due to insufficient input sanitization and output escaping. This allows authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, the plugin only allows administrators access to edit Image Hovers, but if a site admin makes the plugin's features available to lower privileged users through the 'Who Can Edit?' setting, then this can be exploited by those users.

Recommendations For versions up to, and including, 9.7.3, consider disabling the editing of Image Hovers for lower privileged users by adjusting the 'Who Can Edit?' setting to prevent exploitation. As a temporary workaround, restrict access to the Media Image URL value to minimize the risk of arbitrary web script injection. Update to a version later than 9.7.3 when available.
