Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Podman is a tool for managing OCI containers and pods. From 1.8.1 until 5.8.4, a container image that
contains a environment variable with just a key and no value can trick podman into passing that variable
from the host into the container. This is made worse by the fact that using an asterisk (*) will cause
podman to pass all host variables into the container. So essentially a malicious image can exfiltrate all
podman environment variables that are set in the session from where the container is launched. This
vulnerability is fixed in 5.8.4 and 6.0.0. (CVE-2026-57231)

Solution

Update the github.com/containers/podman/v5 library and its related packages to version 5.8.4 or later.
