The vulnerability (CVE-2025-XXXXX/GHSA-XXXX) in the Okta Java SDK stems from a race condition within the shared `ApiClient` instance when handling concurrent HTTP requests. The `ApiClient` class, typically configured as a singleton or shared bean in frameworks like Spring, uses mutable fields to store state related to the current API call, such as HTTP status codes and response headers. When multiple threads execute requests simultaneously using the same client instance, they inadvertently share and overwrite the same internal state variables. This occurs because the client’s execution method lacks proper synchronization or thread-local isolation for per-request response data. Consequently, a rapid sequence of concurrent API calls can cause the status code or headers from one thread’s response to be incorrectly attached to the response object of another, unrelated thread. This cross-contamination of response metadata can lead to application logic errors, such as misinterpreting authentication results or processing data based on another user’s request context.
