Docker Desktop < 4.43.0 Information Disclosure

medium Nessus Plugin ID 300035

Synopsis

The remote host has an application installed that is affected by an information disclosure vulnerability.

Description

The version of Docker Desktop is prior to 4.43.0. It is therefore affected by an information disclosure vulnerability.

- 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. (CVE-2025-6587)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Docker Desktop version 4.43.0 or later
