- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2024-08-30 · Updated: 2026-04-08

## Affected

- MuffinGroup Betheme: through 27.5.6

## Description

The Betheme theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 27.5.6 via deserialization of untrusted input of the 'mfn-page-items' post meta value. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
