Breach of Trust: DuckDuckGo Browser’s AutoConsent JS Bridge…

Security researchers have been sounding the alarm about a critical vulnerability in the DuckDuckGo browser for Android, which leaves users exposed to Universal Cross-Site Scripting (UXSS) attacks. This flaw, discovered in the browser’s AutoConsent JS bridge, allows malicious code from an untrusted source to run on a trusted webpage, compromising user data and potentially leading to identity theft. The vulnerability was reported by security researcher Dhiraj Mishra via HackerOne, a platform that connects bug hunters with companies in need of security testing.

Understanding the AutoConsent JS Bridge Vulnerability

The AutoConsent JS bridge is a feature in the DuckDuckGo browser that enables users to grant or deny permissions for websites to access their browser data. However, the vulnerability in this bridge allows an attacker to bypass the consent mechanism, injecting malicious code onto a trusted webpage. This code can then be used to steal sensitive information, such as login credentials, credit card numbers, or even install malware on the user’s device.

How the Vulnerability Works

1. When a user visits a website, the AutoConsent JS bridge is triggered, allowing the website to request permission to access the user’s browser data.
2. However, an attacker can exploit the vulnerability by injecting malicious code onto the webpage, which is then executed by the browser.
3. The malicious code can then access sensitive information, such as cookies, local storage, or even the user’s browsing history.

Consequences of the Vulnerability

The consequences of this vulnerability are severe, as it can lead to a range of attacks, including:

• Identity theft: An attacker can steal sensitive information, such as login credentials, credit card numbers, or social security numbers.
• Malware installation: Malicious code can be injected onto the user’s device, allowing an attacker to install malware or ransomware.
• Data breaches: Sensitive information can be stolen and sold on the dark web or used for phishing attacks.
