Fluent Forms – Customizable Contact Forms, Survey, Quiz, & Conversational Form Builder 5.1.16 – 6.1.1 – Authenticated (Subscriber+) PHP Object Injection To Arbitrary File Read_CVE-2025-9260

{
    "lastseen": "",
    "description": "The Fluent Forms \u2013 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.\r\nWhile 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",
