Detailsinfo

A vulnerability classified as problematic has been found in Docker Desktop up to 4.42.1. Affected is an unknown function of the component Environment Variable Handler. The manipulation with an unknown input leads to a log file vulnerability. CWE is classifying the issue as CWE-532. Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information. This is going to have an impact on confidentiality. CVE summarizes:

System environment variables are recorded in Docker Desktop diagnostic logs, when using shell auto-completion. This leads to unintentional disclosure of sensitive information such as api keys, passwords, etc.  A malicious actor with read access to these logs could obtain secrets and further use them to gain unauthorized access to other systems. Starting with version 4.43.0 Docker Desktop no longer logs system environment variables as part of diagnostics log collection.
