CVE-2025-22777: 
WordPress vulnerability analysis and mitigation

A critical vulnerability (CVE-2025-22777) has been identified in the GiveWP WordPress plugin, affecting versions through 3.19.3. This Deserialization of Untrusted Data vulnerability allows Object Injection in the popular donation and fundraising plugin, which has over 100,000 active installations worldwide (Security Online).

The vulnerability, with a CVSS score of 9.8, stems from unauthenticated PHP Object Injection through insecure storage of metadata in the database. The flaw exists due to a weak regex check that can be bypassed, allowing attackers to store malicious metadata that would eventually be deserialized. The vulnerability specifically involves the company field in donation forms, where attackers can inject special character sequences like %25F0%259F%2598%25BC to bypass the regex validation (Security Online, WPScan).

The vulnerability enables attackers to perform arbitrary file deletion, including critical files such as wp-config.php, which could lead to full site takeover and remote code execution (RCE). The critical nature of this flaw is particularly concerning given GiveWP's widespread use in donation platforms worldwide (Security Online).

The GiveWP team has released version 3.19.4 to address this vulnerability. Users are strongly advised to update their installations immediately to the latest version to protect their websites (Security Online).
