## Browser Extension Vulnerabilities

Browser extension vulnerabilities refer to security weaknesses within web browser add-ons that can be exploited to compromise user data or manipulate financial activities. In the context of cryptocurrency, these extensions often serve as non-custodial wallet interfaces or portfolio trackers.

If an extension is malicious or poorly coded, it may gain unauthorized access to sensitive information such as private keys, seed phrases, or session cookies. Attackers can leverage these vulnerabilities to perform unauthorized transactions, redirect funds to malicious addresses, or inject phishing prompts directly into legitimate trading interfaces.

Because these extensions operate with broad permissions within the browser environment, they represent a significant attack vector for intercepting order flow or credentials. Users must exercise extreme caution regarding the permissions granted to extensions that interact with decentralized finance platforms.

Regular auditing of extension behavior and limiting access to specific websites can help mitigate these risks. Security relies on the principle of least privilege, ensuring extensions only access what is strictly necessary for their function.

Ultimately, these vulnerabilities pose a direct threat to the integrity of digital asset management.
