What is CVE-2026-6262?
CVE-2026-6262 is a medium-severity path traversal vulnerability in MuffinGroup Betheme, published on 5 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-22
