| Package | Affected versions | Patched versions |
|---|---|---|
| admin columns | < 4.3< 5.5.1 | 4.35.5.1 |
The Admin Columns WordPress plugin before 4.3 and Admin Columns Pro WordPress plugin before 5.5.1 do not sanitise and escape its Label settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
