## What is CVE-2025-9260?

CVE-2025-9260 is a medium-severity unsafe deserialization vulnerability in techjewel Fluent Forms – Customizable Contact Forms, Survey, Quiz, & Conversational Form Builder, published on 2 Sep 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The Fluent Forms – Customizable Contact Forms, Survey, Quiz, & Conversational Form Builder plugin for WordPress is vulnerable to PHP Object Injection in versions 5.1.16 to 6.1.1 via deserialization of untrusted input in the parseUserProperties function. 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 read arbitrary files. If allow_url_include is enabled on the server, remote code execution is possible.
While the vendor patched this issue in version 6.1.0, the patch caused a fatal error in the vulnerable code, due to a missing class import, so we consider 6.1.2 to be the most complete and best patched version

Weakness: CWE-502 (Deserialization of Untrusted Data)
