Deserialization Vulnerability in GiveWP by StellarWP

CVE-2026-82222

What is CVE-2026-82222?

CVE-2026-82222 is a serious deserialization vulnerability affecting the GiveWP plugin developed by StellarWP. This plugin, widely used within the WordPress ecosystem, is designed to streamline donation management for nonprofits, enabling organizations to create and manage donations efficiently. However, this vulnerability allows for object injection through the deserialization of untrusted data, which could lead to significant security risks. When attackers exploit this flaw, they may gain the ability to execute arbitrary code on the server hosting the affected application, compromising its integrity and the data it manages.

The vulnerability affects versions of GiveWP from an unspecified release up to version 4.16.7.1, indicating a critical need for users to maintain updated software to safeguard their systems against potential exploits.

Potential impact of CVE-2026-82222

1. Remote Code Execution: The primary risk posed by this vulnerability is the potential for remote code execution. Attackers can inject malicious code, leading to unauthorized actions being performed on the server, which could facilitate further exploitation, data breaches, or total system compromise.

2. Data Integrity Risks: By leveraging this vulnerability, adversaries could manipulate or destroy sensitive data managed by the GiveWP plugin. This could be particularly damaging for organizations relying on the integrity of donation transactions, potentially leading to financial losses and damage to their reputation.

3. Widespread Exploitation Potential: Given that this vulnerability affects a widely used plugin in the WordPress environment, the risk of exploitation in the wild is heightened. The potential for mass exploitation increases the urgency for users to patch affected systems, as public proof-of-concept exploits could lead to widespread malicious attacks on organizations that are unprepared.
