CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the way application processes environment variables with deprecated Varlink API or the Docker-compatible REST API. If multiple containers are created in a short duration, the environment variables from the first container gets leaked into subsequent containers. A remote user with control over the subsequent containers could use this flaw to gain access to sensitive information stored in such variables.
