WordPress · Stop Spammers Security · CVE-2021-24517
**Name of the Vulnerable Software and Affected Versions**
The Stop Spammers Security | Block Spam Users, Comments, Forms WordPress plugin versions prior to 2021.18
**Description**
The issue allows high privilege users, such as admins, to set Cross-Site Scripting payloads in some settings, even when the unfiltered html capability is disallowed. This is due to the plugin not escaping some of its settings.
**Recommendations**
For versions prior to 2021.18, update to version 2021.18 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's settings for high privilege users until the update is applied.
