Chrome Permission Read and change all your data on all websites: Understanding the Risks and Limitations

Introduction

The latest update to Chrome, specifically version #360, has triggered a broad permission request that has raised security and trust concerns among users. The permission request in question is Read and change all your data on all websites, which may seem alarming to many users. In this article, we will delve into the details of this permission request, explore the potential risks associated with it, and discuss whether it is possible to limit host_permissions to only the necessary to minimize user concerns.

What is the Chrome Permission `Read and change all your data on all websites`?

The Chrome permission Read and change all your data on all websites is a broad permission request that allows extensions to access and modify user data across all websites. This permission is granted when a user installs an extension that requires access to user data, and the user is prompted to grant the permission. The permission is not limited to specific websites or domains, but rather applies to all websites that the user visits.

Potential Risks Associated with the Permission

The broad permission request Read and change all your data on all websites raises several security and trust concerns among users. Some of the potential risks associated with this permission include:

Data Breach: If an extension is compromised or malicious, it can access and steal user data from all websites, including sensitive information such as passwords, credit card numbers, and personal identifiable information.
Data Tampering: An extension with this permission can modify user data on all websites, potentially leading to data tampering, corruption, or even deletion.
Tracking and Profiling: An extension with this permission can track user behavior and collect data on all websites, potentially leading to targeted advertising and profiling.
Security Vulnerabilities: An extension with this permission can potentially exploit security vulnerabilities on all websites, leading to unauthorized access or data breaches.

Limiting Host Permissions to Minimize User Concerns

While the broad permission request Read and change all your data on all websites is necessary for some extensions to function, it is possible to limit host_permissions to only the necessary to minimize user concerns. Here are some ways to limit host_permissions:

Specify Host Permissions: When requesting host permissions, specify the exact permissions required by the extension, rather than requesting broad permissions.
Use Manifest V3: Manifest V3 is a new extension manifest format that allows for more granular control over host permissions. Extensions developed using Manifest V3 can request specific permissions, rather than broad permissions.
Use Content Scripts: Content scripts can be used to access and modify user data on specific websites, rather than accessing data across all websites.
Implement Data Encryption: Implementing data encryption can help protect user data from unauthorized access or tampering.

Best Practices for Extension Developers

To minimize user concerns and ensure the security and trustworthiness of extensions, developers should follow best practices when requesting host permissions. Here are some best practices:

Be Transparent: Clearly explain the purpose of the extension and the permissions required.
Specify Permissions: Specify the exact permissions required by the extension, rather than requesting broad permissions.
Use Manifest V3: Develop extensions using Manifest V3 to take advantage of more granular control over host permissions.
Implement Data Encryption: Implement data encryption to protect user data from unauthorized access or tampering.

Conclusion

The Chrome permission Read and change all your data on all websites is a broad permission request that raises security and trust concerns among users. While this permission is necessary for some extensions to function, it is possible to limit host_permissions to only the necessary to minimize user concerns. By following best practices and using Manifest V3, extension developers can ensure the security and trustworthiness of their extensions and minimize user concerns.
