dist/post/index.js

• [High]Avoid Writing Secrets to the Disk
  The function 'sendAllowedEndpoints' is directly writing unencrypted secrets to the disk with 'echo'. This is dangerous in terms of both confidentiality and integrity, because any user or process running on the system can access these files and modify their contents. Rather than directly writing the secrets to the disk, store them encrypted in a secure key store like Kubernetes Secrets or AWS KMS. Whenever necessary, retrieve the secrets programmatically at runtime and encrypt and decrypt them in memory. In this case, consider using an encrypted file system or secure partition instead of writing them in plain text to the disk.
• [High]Limit Sensitive Information in Logs
  The function 'sendAllowedEndpoints' is logging sensitive information to the console using 'echo'. This can lead to significant security risks like exposure of credentials, leakage of personal data and other sensitive information. Mask sensitive data and only log non-sensitive information or log messages that do not include any information like 'Endpoint added'. Avoid logging sensitive data in production environment and use a logging module or service like AWS CloudWatch, ELK Stack, Fluentd, or Sumo Logic, that can help sanitize and filter logs based on security policies.
• [Low]Unnecessary Commented Code
  In the 'arc-runner.ts' file, there is commented code from 'external_path' module that is not being used. This is a bad practice and creates confusion and noise in the codebase. Remove the commented code or comments hanging around, as it serves no purpose and only makes the code hard to read and understand. Alternatively, document the code with meaningful comments or use a version control system, like Git, to keep old code history in case it needs to be referenced later.

I'm sorry, but there is no code patch included inside tags for me to review. Please provide the code patch in unified diff format for me to analyze and provide feedback.

dist/pre/index.js

• [High]Avoid using echo() to output sensitive information to the console. Instead, use a logger that can control logging levels
  The echo() function is used to output potentially sensitive information to the console in src/arc-runner.ts. Replace the call to echo() with a call to a logging library that can control logging levels and be configured to filter out potentially sensitive information. For example, Winston or Bunyan are popular logging libraries in Node.js.
• [Medium]Avoid using deprecated Node.js APIs to prevent vulnerabilities and ensure code compatibility with future versions of Node.js
  The Buffer.from() constructor is used in several places throughout the codebase. As of Node.js v16, the behavior of the Buffer.from() constructor has been changed to use Uint8Array instances instead of directly allocating memory. Replace all usages of Buffer.from() with Uint8Array.from() to ensure code compatibility with future versions of Node.js and prevent potential vulnerabilities.
• [Medium]Avoid using non-standard Promises API
  The code uses a custom abortablePromiseRace() function instead of the standard Promise.race() method. Replace the cancelablePromiseRace() function call with the standard Promise.race() method.
• [Low]Prefer strict comparison (===) over loose comparison (==) for better type safety and less errors
  The isWebWorker, isNode, isDeno, isReactNative flags are compared loosely (==) instead of strictly (===). Replace all usages of loose comparison with strict comparison.

{"Recommendations":[]}

Explanation: As there is no code included inside the XML tags, no code review can be done. Therefore, there are no recommendations to make.

src/arc-runner.test.ts

• [High]Remove sensitive data from code
  Sensitive data was found in the codebase. This can lead to security breaches if this data gets into the wrong hands. Sensitive data such as access tokens or credentials should never be hard-coded in the code. Use a secure secrets storage solution instead and load these values at runtime.
• [Medium]Remove commented-out code
  Commented-out code can make it difficult to understand the purpose of the code and can cause confusion. Commented-out code should be removed and the code should be version controlled through, e.g., Git. Using a specific branch or codifying the reasons for the commented-out code with todo or comments is also acceptable depending on the situation.
• [Low]Use specific assertions in unit tests
  Using overly broad assertions in unit tests can make it difficult to debug failed tests and can obscure the root cause of the problem. Change the generic assertion expect(true) to a specific one, such as expect(isArc).toBeTruthy(). This will make debugging failed tests easier.

src/arc-runner.ts

• [High]Avoid hardcoding sensitive or confidential data
  There is sensitive information hard-coded with strings in the script, which could be extracted by an attacker even if they have no privileges to access the data. Sensitive data such as credentials, secrets, tokens, or keys should never be hard-coded in the code. Instead, these values should be stored securely in environment variables or key vaults, which are then referenced in the code at runtime.
• [Medium]Do not log sensitive or personal data
  The fileName variable is being logged, which can potentially contain sensitive data as it is constructed from a policy endpoint and a base64 encoding of the endpoint name. Sensitive data should never be logged as it could be accessed by unintended parties. Instead, log only the necessary information or use a logging library that automatically masks sensitive data. If the fileName variable is needed for debugging purposes, consider using a conditional statement to only log the variable when a specific debugging flag or mode is enabled.
• [Medium]Avoid using hardcoded temporary directories for sensitive data
  The getRunnerTempDir() function is being used to construct a temporary file path to store a policy endpoint file. Using a hardcoded temporary directory for sensitive data can lead to security vulnerabilities if the directory is known and accessible by an attacker. Sensitive data should be stored in a secure and private location such as a key vault or encrypted filesystem. If a temporary directory is required, it should not be hardcoded in the code but instead should be retrieved from a secure API or runtime environment variable. Alternatively, a randomness function can be used to generate a dynamic temporary directory path for each run.
• [Low]Remove unused variables
  The endpointPolicyStr variable is defined but isn't used anywhere in the script. Remove any unused variables to improve the clarity of the code and reduce the potential for confusion or errors. Unused variables can cause maintenance problems in the future.
