Hubuum Client Library: Potential Sensitive Data Exposure Through Diagnostics

EARLY WARNING · UNCONFIRMED. This page describes a developing threat that 0Day surfaced from early signals and has not yet independently confirmed. Details may change. Always verify against the primary sources before acting.
GHSA-2625-RW7M-5Q5XSeverity: HIGH

An early warning has been issued regarding the Hubuum client library, which reportedly may expose sensitive data through its default diagnostics. Users of affected versions should upgrade to 0.6.1 and review their logs.

What happened

The Hubuum client library, specifically versions introduced between 0.0.1 and 0.6.0, appears to expose sensitive request, response, import/export, task, delivery, or server-provided data when applications format or log errors and public models. This exposure is under investigation and is associated with the Hubuum client's default diagnostics functionality.

To assess your exposure, check if your application uses any version of the Hubuum client within the affected range (0.0.1 to 0.6.0). If so, it is recommended to upgrade to version 0.6.1, which reportedly fixes the issue. Additionally, review your application logs for any signs of sensitive data exposure.
