Report
The underConstruction WordPress plugin before 1.21 does not sanitise or escape the "Display a custom page using your own HTML" setting before outputting it, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiletred_html capability is disallowed.
Score:4.8
Severity:Medium
Version: 1.20
There is a patch available in v1.21 and we strongly recommend you update to this version as soon as possible.
