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

Name of the Vulnerable Software and Affected Versions: CYAN Backup WordPress plugin versions prior to 2.5.3

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 2.5.3, update to version 2.5.3 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 can be applied.
