Overview
The CVE-2025-24779 vulnerability is a deserialization weakness in NooTheme Yogi, a popular WordPress theme. This vulnerability opens the door for an attacker to inject malicious objects into the system, potentially leading to a full system compromise or significant data leakage. This vulnerability affects a wide range of versions, specifically those from an unspecified initial release up to version 2.9.0, making it a critical concern for all users of the NooTheme Yogi.

How the Exploit Works
An attacker exploits this vulnerability by sending an object containing malicious code to the vulnerable program. This tactic is known as “Object Injection.” Since the NooTheme Yogi does not adequately validate or sanitize the incoming objects before deserialization, the malicious code within the object is executed when the object is deserialized. This can lead to harmful consequences such as system compromise or leakage of sensitive data.
Conceptual Example Code
Here’s a conceptual example of how an attacker might exploit this vulnerability:
POST /wp-content/themes/yogi/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_object": "{ serialized_object_with_malicious_code }" }In this example, the attacker sends a POST request to a vulnerable endpoint on the target system. The request includes a JSON object with a malicious serialized object. When the server deserializes this object, it inadvertently executes the malicious code, leading to potential system compromise or data leakage.
Mitigation Measures
To mitigate this vulnerability, users of NooTheme Yogi are advised to apply the patch provided by the vendor, which fixes the deserialization flaw. If the patch cannot be applied immediately, users may also implement a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary measure to detect and block exploit attempts. However, these are not long-term solutions and do not address the root cause of the vulnerability. It is strongly recommended to apply the vendor patch as soon as possible.
