WordPress · Custom Base Terms · CVE-2023-2600
**Name of the Vulnerable Software and Affected Versions**
Custom Base Terms WordPress plugin versions prior to 1.0.3
**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 a multisite setup. This is due to the plugin not sanitizing and escaping some of its settings.
**Recommendations**
For versions prior to 1.0.3, update to version 1.0.3 or later to resolve the issue. As a temporary workaround, consider restricting the ability of high-privilege users to modify plugin settings until the update is applied.
