Tracked as CVE-2025-24601, this vulnerability allows for object injection through the deserialization of untrusted data. This flaw has the potential to enable remote code execution, jeopardizing the confidentiality, integrity, and availability of affected systems. This article will explore the technical aspects of this vulnerability, the affected versions, and the necessary steps to remediate this serious security risk. It aims to provide a comprehensive guide for security professionals to effectively secure their environments.

A Short Introduction to ThimPress FundPress

FundPress is a WordPress plugin developed by ThimPress, designed to facilitate crowdfunding campaigns directly within WordPress websites. It provides functionalities for creating, managing, and supporting crowdfunding projects, allowing users to contribute financially to initiatives. FundPress offers a range of features including project creation, donation management, user roles, and reporting. The plugin is used by a variety of organizations and individuals to raise funds for various causes, making its security critical for maintaining the trust and integrity of the involved transactions and data. Given its role in financial transactions, any vulnerability in FundPress has the potential to cause significant harm.

Summary of CVE-2025-24601

The vulnerability, identified as CVE-2025-24601, involves the deserialization of untrusted data within the ThimPress FundPress plugin. Specifically, the plugin fails to adequately sanitize or validate input data before passing it to the PHP unserialize() function. This function, when used with untrusted data, can allow for the instantiation of arbitrary objects, leading to object injection vulnerabilities. An attacker can craft malicious serialized data that, when deserialized, could lead to the execution of arbitrary code. This flaw arises from the plugin's reliance on user-supplied data without adequate sanitization. The absence of input validation allows for the manipulation of serialized data, resulting in the execution of unauthorized code or other harmful operations. This makes it imperative that all users of the plugin understand and fix the flaw to prevent any exploitation.

Impact of CVE-2025-24601

The impact of CVE-2025-24601 is severe due to its potential to enable remote code execution on the server hosting the vulnerable WordPress site. With a CVSS base score of 9.8, this vulnerability is considered critical. Successfully exploiting this flaw allows an attacker to take complete control of the server, granting them the ability to execute arbitrary commands, modify files, steal sensitive data, or launch further attacks within the network. This can lead to complete compromise of the website and its associated data, including user credentials and financial information. The lack of any requirement for user interaction or privileges makes this flaw particularly dangerous, as it can be exploited remotely with ease. The impact on confidentiality, integrity, and availability is high, making it vital for all users to take immediate action to secure their systems.
