CVE-2023-2254: Ko-Fi Button

Medium severity, CVSS 4.8. EPSS: 0.4% chance of exploitation in the next 30 days.

The Ko-fi Button WordPress plugin before 1.3.3 does not properly some of its settings, which could allow high-privilege users to perform Stored Cross-Site Scripting (XSS) attacks even when the unfiltered_html capability is disallowed (for example in multisite setup), and we consider it a low risk.

Affected products

• Ko-Fi Ko-Fi Button: before 1.3.3 (fixed in 1.3.3)
