Description

In v2.0.x, access tokens are issued per thread. However, credentials are shared. This can lead to inconsistencies in access tokens between threads. Specific issues that can occur are as follows:

  • Token refreshes occur as many times as the number of threads.
  • Credentials are shared, so when multiple threads simultaneously refresh or read a token, it may become outdated.

Research direction

No source file, test, or entry point is identified in the report. Trace how v2.0.x issues and stores access tokens and shares credentials across threads, then reproduce concurrent refresh and read scenarios. Done means token handling remains consistent across threads without redundant refreshes or stale credentials.
