CVE-2024-5346

Name of the Vulnerable Software and Affected Versions Flatsome theme for WordPress versions up to, and including, 3.18.7

Description The issue is related to Stored Cross-Site Scripting via the UX Countdown, Video Button, UX Video, UX Slider, UX Sidebar, and UX Payment Icons shortcodes due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations For versions up to, and including, 3.18.7, update to a version later than 3.18.7 to resolve the issue. As a temporary workaround, consider restricting access to the UX Countdown, Video Button, UX Video, UX Slider, UX Sidebar, and UX Payment Icons shortcodes for users with contributor-level access and above until a patch is available.
