WordPress Plugin Vulnerabilities
Slider, Gallery, and Carousel by MetaSlider < 3.27.9 - Admin+ Stored Cross Site Scripting
Description
The plugin does not sanitise and escape some of its Gallery Image parameters, 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
Add an image to a Gallery (via MetaSlider > Gallery Beta) and put the following payload in the "Alt Text" setting: "><img src onerror=alert(/XSS/)>
