CVE-2026-6262: Muffingroup Betheme

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

The Betheme theme for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 28.4. This is due to the upload_icons() function workflow using a user-controlled upload path (`mfn-icon-upload`) in a filesystem move operation without constraining it to the uploads directory. This makes it possible for authenticated attackers, with contributor-level access and above, to move/delete arbitrary local files via path traversal.

Affected products

• Muffingroup Betheme: up to and including 28.4
