Name of the Vulnerable Software and Affected Versions SVG Support WordPress plugin versions prior to 2.3.20

Description The issue allows high privilege users to perform Cross-Site Scripting attacks due to the lack of escaping in the CSS Class to target setting before it is outputted in an attribute. This can occur even when the unfiltered html capability is disallowed.

Recommendations For versions prior to 2.3.20, update to version 2.3.20 or later to resolve the issue. As a temporary workaround, consider restricting the use of the CSS Class to target setting to minimize the risk of exploitation.
