Base vector

AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions EventON WordPress plugin versions prior to 2.2

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 2.2, update to version 2.2 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.
