Medium

Base vector

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

Name of the Vulnerable Software and Affected Versions: Subscribe to Comments plugin for WordPress versions up to, and including, 2.3

Description: The issue is related to Reflected Cross-Site Scripting due to the use of add query arg without appropriate escaping on the URL. This allows unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Recommendations: For versions up to, and including, 2.3, update to a version that properly escapes the URL to prevent the injection of arbitrary web scripts. As a temporary workaround, consider restricting access to the Subscribe to Comments plugin until a patch is available.
