Summary

  • ProviderRegistryRecord was being interpolated directly into log/error messages in the provider registry sync cron job, which exposed the variables dict containing secrets (API keys, tokens, etc.)
  • Replaced {provider_record} with {provider_record.location} in 4 log/error message sites

Test plan

  • Verify mise run check passes
  • Trigger a provider registry sync and confirm logs no longer contain env variables

ProviderRegistryRecord was interpolated directly into log and error
messages, exposing the variables dict which can contain secrets.
Log only provider_record.location instead.

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a security vulnerability by preventing the unintentional logging of sensitive provider environment variables. Previously, ProviderRegistryRecord objects, which contain confidential variables, were directly interpolated into log and error messages during the provider registry synchronization process. The changes ensure that only the non-sensitive provider_record.location is logged, thereby enhancing security and preventing potential information leaks.

Highlights

  • Security Fix: Prevented sensitive provider environment variables from being inadvertently logged during the provider registry synchronization process.
  • Logging Improvement: Modified log and error messages to display only the non-sensitive provider_record.location instead of the entire ProviderRegistryRecord object.

Code Review

This pull request addresses a critical security vulnerability by preventing provider environment variables, which may contain secrets, from being leaked into log messages. The change correctly replaces logging the entire ProviderRegistryRecord object with just its location attribute. This is an important fix. I've also noticed a minor issue with a potentially misleading error message in one of the modified lines and have left a suggestion for improvement.

logger.info(f"Updated provider {provider_record.location}")
except Exception as ex:
errors.append(RuntimeError(f"[{provider_record}]: Failed to add provider: {ex}"))
errors.append(RuntimeError(f"[{provider_record.location}]: Failed to add provider: {ex}"))

medium

This error message appears to be copied from the 'new providers' loop. For clarity, since this code block handles updating existing providers via patch_provider, it would be better if the message reflected that an update failed, not an addition.

Suggested change
errors.append(RuntimeError(f"[{provider_record.location}]: Failed to add provider: {ex}"))
errors.append(RuntimeError(f"[{provider_record.location}]: Failed to update provider: {ex}"))
