TIMELINE Jun 17 Reserved by GitHub_M Jun 26 EXPLOIT PUBLISHED — CVE-2026-55686 (podman-container-tools podman). Public exploit reference added. Jun 26 Published (CNA: GitHub_M)
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.
