## What is CVE-2025-14476?

CVE-2025-14476 is a high-severity unsafe deserialization vulnerability in unitecms Doubly – Cross Domain Copy Paste for WordPress, published on 13 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The Doubly – Cross Domain Copy Paste for WordPress plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.0.46 via deserialization of untrusted input from the content.txt file within uploaded ZIP archives. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to execute arbitrary code, delete files, retrieve sensitive data, or perform other actions depending on the available gadgets. This is only exploitable by subscribers, when administrators have explicitly enabled that access.

Weakness: CWE-502 (Deserialization of Untrusted Data)
