| Package | Affected versions | Patched versions |
|---|---|---|
| underconstruction | < 1.21 | 1.21 |
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.
