DescriptionNVD

The Betheme theme for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 28.4.

This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files (including PHP) and achieve remote code execution via the Icons icon-pack upload flow.
