CVE-2023-2600: Artprojectgroup Custom Base Terms

Medium severity, CVSS 4.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The Custom Base Terms WordPress plugin before 1.0.3 does not sanitize and escape some of its 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)

Affected products

• Artprojectgroup Custom Base Terms: before 1.0.3 (fixed in 1.0.3)
