**Name of the Vulnerable Software and Affected Versions** gAppointments WordPress plugin versions 1.9.5.1 and earlier **Description** The issue concerns the gAppointments WordPress plugin, which does not properly sanitise and escape some of its settings. This 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 gAppointments WordPress plugin versions 1.9.5.1 and earlier, update to a version that addresses the sanitisation and escaping of settings to prevent Stored Cross-Site Scripting attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** gAppointments WordPress plugin versions prior to 1.10.0 **Description** The issue is related to a Reflected Cross-Site Scripting problem. It occurs because a parameter is not properly sanitised and escaped before being outputted back in the page. This could be exploited against admin users. **Recommendations** For versions prior to 1.10.0, update to version 1.10.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's functionality to minimize the risk of exploitation.
