PHP object injection in Prime Mover WordPress plugin allows unauthenticated attackers to execute code when admins perform routine backups; update immediately.

Critical · CVSS 9.8CVE-2026-115806

### [Prime Mover WordPress Plugin – Unauthenticated Remote Code Execution via Object Injection](https://securexion.com/cve-2026-115806/)

The Prime Mover backup and migration plugin for WordPress contains an unsafe deserialization flaw in its search-and-replace routine that accepts untrusted, base64-encoded serialized objects from comment fields. An attacker can inject a malicious object that exploits a Property-Oriented Programming chain in the bundled Freemius library to execute arbitrary code when an administrator runs a backup or restore operation.

**What to do:** Audit all Prime Mover installations and upgrade to version 2.2.2 or later immediately; if unavailable, disable the plugin until a patch is confirmed.
