WordPress Plugin Vulnerabilities
Image Hover Effects < 5.5 - Admin+ Stored XSS
Description
The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
Proof of Concept
Go to the plugin settings (Image Hover Effects > Image Hover Effects) and put the following payload in any input field (such as Category Name, Caption Description, Caption Heading, etc.) and save: "><img src=x onerror=alert(/XSS/)> The XSS will be triggered when accessing the settings again, as well as in posts/pages where the caption is embedded via shortcode.
