WordPress · Metaslider · CVE-2022-2823
**Name of the Vulnerable Software and Affected Versions**
The Slider, Gallery, and Carousel by MetaSlider WordPress plugin versions prior to 3.27.9
**Description**
The issue concerns the lack of sanitization and escaping of certain Gallery Image parameters, which could allow high-privilege users, such as administrators, to perform Stored Cross-Site Scripting attacks. This is possible even when the unfiltered html capability is disallowed, for example, in a multisite setup.
**Recommendations**
For versions prior to 3.27.9, update to version 3.27.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the Gallery Image parameters to minimize the risk of exploitation.
