CVE-2022-2374

Name of the Vulnerable Software and Affected Versions Simply Schedule Appointments WordPress plugin versions prior to 1.5.7.7

Description The issue allows high privilege users, such as admins, to perform Stored Cross-Site Scripting attacks. This can occur even when the unfiltered html capability is disallowed, for example, in a multisite setup. The problem arises because some settings are not properly sanitised and escaped.

Recommendations For versions prior to 1.5.7.7, update to version 1.5.7.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's settings for high privilege users until the update is applied.
