WordPress · Wordpress Online Booking/Scheduling Plugin · CVE-2023-5209
**Name of the Vulnerable Software and Affected Versions**
WordPress Online Booking and Scheduling Plugin versions prior to 22.5
**Description**
The issue allows high privilege users, such as admins, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example, in multisite setups. This is due to the plugin not sanitizing and escaping some of its settings.
**Recommendations**
For versions prior to 22.5, update to version 22.5 or later to resolve the issue. As a temporary workaround, consider restricting the ability of high privilege users to access and modify the plugin's settings until the update is applied.
