[Feature] [Phase-1] Enhance access control with Rich Authorization Requests (RFC 9396)

[VimukthiRajapaksha]

Description

Traditional OAuth 2.0 requires third-party applications to request broad permissions to access protected resources. This leads to:

• Unnecessary Data Access: Applications may access data and resources that they do not need, increasing the risk of privacy breaches and data misuse.
• Limited User Control: Users may not be aware of the extent of permissions they grant, limiting their control over data usage.

For example imagine a third-party fitness app that nudges you to take breaks during your workday. To track your activity and remind you to move, it wants to access your smartwatch's health data. The app requests a broad "health_data:read" scope. You have no choice but to grant access to everything, including sensitive data like heart rate, blood pressure, and sleep patterns, even if the app only needs your step count during the office hours.

Third-party applications accessing more data than necessary increases the risk of privacy breaches and unauthorized data use, potentially compromising sensitive information like health records or financial data.

Release note for the intended audience

Strengthens the security of OAuth 2.0-based integrations by adopting granular permissions aligned with the RFC 9396 specification. Key benefits include:

• Reduced Data Exposure: Clients can now request specific data permissions instead of broad scopes, minimizing the amount of user data accessible.
• Improved User Control: Granular permissions empower users to grant applications access to only the data they deem necessary.
• Enhanced Compliance: Adherence to RFC 9396 standards ensures compatibility with other compliant systems and promotes industry best practices in data security.
