Severity: High (7.5 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

messageformat | < 2.3.0 How the Exploit Works

The vulnerability arises from the package’s improper handling of message key paths when processing nested message keys containing special characters such as __proto__. This can lead to unintended modification of the JavaScript Object prototype, a phenomenon known as prototype pollution. A remote attacker can take advantage of this flaw to inject properties into the global object prototype via specially crafted message input, creating potential for denial of service attacks or other undefined behaviors.

Conceptual Example Code

Below is a conceptual example demonstrating how the vulnerability might be exploited:

let malicious_payload = {
"__proto__.polluted": "Prototype polluted!"
};
messageformat.format(malicious_payload);

Following execution of the above code, all objects in the affected JavaScript context will have a “polluted” property with the value “Prototype polluted!”. This could be used to manipulate or disrupt the normal operation of the application.

Overview

The vulnerability CVE-2025-57330 is a Prototype Pollution issue in the web3-core-subscriptions package. This package is widely used to manage web3 subscriptions, and the vulnerability affects all versions up to 1.10.4. This issue could potentially allow an attacker to cause a Denial of Service (DoS) to the system, compromise it, or even leak sensitive data, hence the need for immediate attention and mitigation.

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise, data leakage, and potential for DoS

Affected Products

Product | Affected Versions

web3-core-subscriptions | 1.10.4 and before

How the Exploit Works

The exploit works by an attacker injecting properties into Object.prototype via a carefully crafted payload. This payload can be delivered through network interaction with the application using the vulnerable package. The injection can modify the core behavior of the application, causing it to crash (Denial of Service) or behave unpredictably, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of a malicious payload that could exploit this vulnerability:

POST /web3/subscribe HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"__proto__": {
"shutdown": true
}
}

In this example, if the server parses this JSON and merges it into their application state, it could trigger unwanted behavior like shutting down the system or service. Please note that this is a simplified example and real exploit code may be more complex and less obvious.

Overview

The vulnerability CVE-2025-48869 pertains to the Horilla Human Resource Management System (HRMS), a widely-used free and open-source HRMS.
