{"id":"CVE-2026-54319","aliases":["GHSA-fjv8-j4p5-cr9m","GO-2026-5367"],"url":"https://o3.security/vulnerability/CVE-2026-54319","summary":"Daytona: Path traversal in sandbox volume id mounts arbitrary host paths into the sandbox — cross-tenant data access and host escape","details":"Daytona is a secure and elastic infrastructure runtime for AI-generated code execution and agent workflows. Prior to 0.186, a sandbox volume reference (volumeId, which may also be a volume name) was forwarded to the runner and used to build the host bind-mount source path without confinement. A reference containing path-traversal sequences could in principle resolve the mount source outside the intended per-volume base directory. This vulnerability is fixed in 0.186.","published":"2026-06-23T18:08:54.734Z","modified":"2026-08-12T03:51:18.922648168Z","cvss":{"score":4.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"},"epss":{"score":0.00243,"percentile":0.15327,"asOf":"2026-09-02"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/daytonaio/daytona","fixedVersion":"0.186.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54319.json"},{"type":"ADVISORY","url":"https://github.com/daytonaio/daytona/security/advisories/GHSA-fjv8-j4p5-cr9m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54319"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:18.922648168Z"}}
