Podman Improper Certificate Validation; machine missing TLS verification

High severity GitHub Reviewed Published Jun 24, 2025 in podman-container-tools/podman • Updated Nov 29, 2025

Package

gomod github.com/containers/podman/v4 (Go)

Affected versions

>= 4.8.0, <= 4.9.5

Patched versions

None
gomod github.com/containers/podman/v5 (Go)
< 5.5.2
5.5.2

Description

Impact

The podman machine init command fails to verify the TLS certificate when downloading the VM images from an OCI registry (which it does by default since 5.0.0) allowing a possible Man In The Middle attack.

Patches

podman-container-tools/podman@726b506
Fixed in v5.5.2

Workarounds

Download the disk image manually via some other tool that verifies the TLS connection. Then pass the local image as file path (podman machine init --image ./somepath)

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
