CVE-2022-3618: Clevelandwebdeveloper Spacer

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

The Spacer WordPress plugin before 3.0.7 does not sanitize and escapes 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

• Clevelandwebdeveloper Spacer: before 3.0.7 (fixed in 3.0.7)
