CVE-2026-55686: Podman: WORKDIR symlink traversal vulnerability

• Severity: medium (CVSS 5.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-06-26 · updated 2026-10-25
• Weakness: CWE-61

Description

Podman is a tool for managing OCI containers and pods. From 3.0.0 until 5.7.1, running a malicious container image where the WORKDIR path contains a symlink can create a directory or modify ownership on the host filesystem. Modified ownership is less likely to happen as that requires help from an untrusted/malicious process that mutates the host filesystem tree during dereferencing of the WORKDIR path, to trigger a race condition. This vulnerability is fixed in 5.7.1.

Affected products

• podman: from 3.0.0 before 5.7.1 — fixed in 5.7.1

How to fix

Upgrade to a fixed version: podman 5.7.1. Check the vendor advisory for mitigations.
