WordPress · Sendpress Newsletters · CVE-2024-1589
**Name of the Vulnerable Software and Affected Versions**
SendPress Newsletters WordPress plugin versions 1.23.11.6 and earlier
**Description**
The issue allows high privilege users, such as admins, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example, in multisite setups. This is due to the plugin not sanitizing and escaping some of its settings.
**Recommendations**
For SendPress Newsletters WordPress plugin versions 1.23.11.6 and earlier, update to a version later than 1.23.11.6 to resolve the issue.
As a temporary workaround, consider restricting access to the plugin's settings for high privilege users until a patch is available.
