Hello,

This is our first PR and we hope that our changes will be helpful to the community. We have run make format, make lint and make test locally before submitting the PR. To our knowledge, our changes do not introduce any new errors.

Our PR has added basic tools to interact with Microsoft Graph Api that can send or read user's emails. Classes to complete the authentication flows are also added to perform user login or provide accessToken that must be used for Microsoft Graph. Nonetheless, we have added tests to test our changes, note the test is dependent on the necessary credentials in .env . These changes were put together by me, @oscarchen178, @Qi123123Li, and @SimonLi1020 We're a group of students from UofT submitting this for a project. Please test the code and let us know if there are any issues.

Thank you in advance to the maintainers for their time.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Security Issue: Access Token Storage

Storing the access token directly in the OutlookIntegration class as a property poses a security risk. If the codebase is compromised, an attacker could gain access to the stored access token and misuse it to access user data or perform unauthorized actions.

Actionable Feedback:

  • Avoid storing sensitive information like access tokens directly in the code.
  • Use a secure storage mechanism such as environment variables or a secrets management system to store the access token.
  • Retrieve the access token from the secure storage when needed, rather than storing it in the code.

By following these recommendations, you can enhance the security of your application and protect user data from unauthorized access.

category Error Handling

In the readEmails and sendEmail methods, you are catching errors, logging them to the console, and then re-throwing the errors using throw error. This can lead to unhandled promise rejections if the caller of these methods does not catch and handle the re-thrown errors. Consider removing the throw error statements and instead return an error response or a default value to indicate that an error occurred. This allows the caller to handle the error appropriately based on the returned value.

Security Issue: Error Handling and Logging

The error handling in the readEmails and sendEmail methods could potentially leak sensitive information. When an error occurs, the error details are logged using console.error, which may include sensitive information such as the access token or other details about the API request.

Actionable Feedback:

  • Avoid logging the entire error object or sensitive information directly.
  • Log a generic error message that does not include sensitive details.
  • If logging is necessary for debugging purposes, ensure that the logs are properly secured and accessible only to authorized personnel.
  • Consider using a logging framework that allows you to control the level of detail logged based on the environment.

By handling errors carefully and avoiding the logging of sensitive information, you can prevent unauthorized access to sensitive data and maintain the security of your application.

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪
🧪 No relevant tests
🔒 Security concerns

Sensitive information exposure:
The accessToken is stored as a class property. While not directly exposed, it's a sensitive piece of information that should be handled with care. Consider using a more secure method of token management, such as storing it in a secure credential store or using short-lived tokens.

⚡ Key issues to review

Error Handling
The error handling in the readEmails and sendEmail methods could be improved. Currently, errors are logged and then re-thrown, which may not be the most user-friendly approach.

Type Safety
The Email interface is incomplete. It only defines sender and subject, but the comment suggests there are other properties. This could lead to type safety issues.

Unused Code
There's commented-out code at the end of the file that should be removed before merging.
