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."}], "lastModified": "2026-06-26T19:53:30.177", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:podman_project:podman:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "62FDCF49-B6FD-4F79-9101-8920CF9CC3D3", "versionEndExcluding": "5.7.1", "versionStartIncluding": "3.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
