CVE-2025-32145: Critical Deserialization of Untrusted Data Vulnerability in WPEvently

Overview

The Common Vulnerabilities and Exposures (CVE) system has recently identified a critical vulnerability, CVE-2025-32145, that affects the magepeopleteam WpEvently. This vulnerability presents a significant cybersecurity threat due to its capacity for Object Injection via Deserialization of Untrusted Data. Notably, this vulnerability affects versions up to and including 4.3.5 of the WpEvently software. As a consequence, any system or entity utilizing these versions of WpEvently is at high risk of system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-32145

Product | Affected Versions

magepeopleteam WpEvently | n/a – 4.3.5

How the Exploit Works

The vulnerability exploits the process of deserialization, where the software does not validate or incorrectly validates input that can alter the control flow or data flow of a program. In this case, an attacker can serialize malicious data that, when deserialized by the WpEvently, results in Object Injection. This malicious object can then be used to execute functions within the context of the application, potentially leading to unauthorized access, data leakage, or even a complete system compromise.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited. This pseudocode is a representation of a HTTP request carrying a malicious payload.

POST /WpEvently/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_object": "Serialized malicious object data" }

In this example, the “malicious_object” is serialized data that, when deserialized by the affected software, could lead to unintended consequences, such as unauthorized system access or data leakage.

Mitigation Guidance

It’s highly recommended that users of WpEvently immediately apply the vendor-provided patch to address this vulnerability. If the patch cannot be immediately applied, users should consider employing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation solution. These measures will help protect the system until the patch can be applied.
