| Package | Affected versions | Patched versions |
|---|---|---|
| newsletter | < 8.8.2 | 8.8.2 |
The Newsletter WordPress plugin before 8.8.2 does not sanitise and escape some of its Subscription 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).
