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":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"podman-container-tools","product":"podman","versions":[{"version":">= 3.0.0, < 5.7.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-26T18:31:12.071003Z","id":"CVE-2026-55686","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-61"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:podman_project:podman:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0.0","versionEndExcluding":"5.7.1","matchCriteriaId":"62FDCF49-B6FD-4F79-9101-8920CF9CC3D3"}]}]}],"references":[{"url":"https://github.com/podman-container-tools/podman/commit/d18e44e9abb3bf5b7294aa70806e1368fdddfdd0","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-q6r4-3wmg-fwcq","source":"security-advisories@github.com","tags":["Exploit","Patch","Vendor Advisory"]},{"url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-q6r4-3wmg-fwcq","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Patch","Vendor Advisory"]}]}
