CVE-2021-24568

Name of the Vulnerable Software and Affected Versions AddToAny Share Buttons WordPress plugin versions prior to 1.7.46

Description The issue allows high privilege users, such as admins, to perform Cross-Site Scripting attacks. This is possible because the plugin does not sanitize its Sharing Header setting when outputting it in frontend pages, even when the unfiltered html capability is disallowed.

Recommendations For versions prior to 1.7.46, update to version 1.7.46 or later to resolve the issue. As a temporary workaround, consider restricting the ability to modify the Sharing Header setting to trusted users only.
