Summary:

The code changes in this pull request cover various updates to the Cedarling project, including a README update, documentation improvements, and schema changes. While the majority of the changes do not introduce any obvious security concerns, there are a few areas that warrant closer attention from an application security perspective.

The key security-related aspects of these changes include:

1. Dependency Management and Build Process: The changes to the cedarling_python README highlight the importance of properly managing dependencies and ensuring a secure build process to mitigate potential security vulnerabilities.

2. Token Handling: The updates to the cedarling_python.pyi file introduce new parameters for handling ID tokens and userinfo tokens, which requires thorough validation and secure storage of these tokens to prevent security issues like token tampering or replay attacks.

3. Policy-based Authorization: The changes to the policy store and the example usage demonstrate the application's use of a policy-based authorization framework, which is a security-focused approach. However, it's crucial to ensure that the policies are defined and implemented correctly to enforce the desired access control rules.

4. Data Model Updates: The changes to the Cedarling schema, including the introduction of new entity types and the modification of optional fields, should be carefully reviewed to ensure that the application's authentication, authorization, and data validation mechanisms are not compromised.

Files Changed:

1. jans-cedarling/bindings/cedarling_python/README.md: The changes in this file are minor, correcting a typo, but the overall README provides important information about dependency management, the build process, and testing, which are security-relevant aspects.

2. docs/cedarling/python/usage.md: The updates to this documentation file demonstrate the usage of the Cedarling authorization framework, highlighting the use of a policy store and the separation of concerns between different principal types, which are positive security practices.

3. jans-cedarling/bindings/cedarling_python/cedarling_python.pyi: The changes in this file introduce new parameters for handling ID tokens and userinfo tokens, which requires careful review and implementation of token validation and secure storage.

4. jans-cedarling/bindings/cedarling_python/example.py: The example script showcases the integration of the Cedarling library, including the use of policy-based authorization, context-aware decision-making, and token handling, which are important security considerations.

5. jans-cedarling/bindings/cedarling_python/example_files/policy-store.json: The updates to the policy store definitions demonstrate the application's access control mechanisms, which should be thoroughly reviewed to ensure the policies are correctly defined and implemented.

6. jans-cedarling/schema/cedarling_core.cedarschema and jans-cedarling/schema/cedarling_core.json: The changes to the Cedarling schema, including the introduction of new entity types and the modification of optional fields, should be carefully reviewed to ensure that the application's data model and validation processes are secure.
