A reference\ncontaining path-traversal sequences could in principle resolve the mount source outside the\nintended per-volume base directory.\n\n## Impact\nHad the traversal been reachable, an authenticated user could have caused the runner to\nbind-mount an unintended host path into their sandbox, with a worst-case impact of read and\nwrite access to other tenants' volume data (per-volume FUSE mounts are world-readable and\nwritable).\n\nImportant: this path was not exploitable in any released version. A volume reference is\nvalidated against the database before it reaches the runner, and the volume id column is a\nUUID type, so a reference containing traversal sequences is rejected at validation time and\nthe request fails before any mount is constructed. We could not reproduce cross-tenant access\nor an out-of-base host mount on a released build; the observable effect of the documented\npayload was a server-side validation error. Severity is assessed as Medium on that basis.\n\n## Patches\nFixed in v0.186.0. Volume references are now resolved to the canonical volume UUID\nserver-side before reaching the runner, so a name can never flow downstream as a path\ncomponent, and the runner confines the mount source to the volume base directory and rejects\nany non-UUID reference.\n\n## Workarounds\nUpgrade to v0.186.0 or later. No configuration workaround is required for released versions,\nwhich were not exploitable.\n\n## Credit\nReported by @vnth4nhnt from CyStack.","state":0,"publishedAt":"2026-06-18T17:19:51+00:00","modifiedAt":"2026-07-20T21:30:34.8145003+00:00","affected":[{"ecosystem":"Go","name":"github.com/daytonaio/daytona","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.186.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/daytonaio/daytona/security/advisories/GHSA-fjv8-j4p5-cr9m","https://nvd.nist.gov/vuln/detail/CVE-2026-54319","https://github.com/daytonaio/daytona"],"sourceUrl":"https://github.com/advisories/GHSA-fjv8-j4p5-cr9m","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-fjv8-j4p5-cr9m","identifiers":["GHSA-fjv8-j4p5-cr9m","CVE-2026-54319","GO-2026-5367"]},"retained":false,"historicalAffected":[]},{"revision":"ffb6603825b845b2b7f356d875cae898","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-5367","aliases":["CVE-2026-54319","GHSA-fjv8-j4p5-cr9m"],"title":"Daytona: Path traversal in sandbox volume id mounts arbitrary host paths into the sandbox — cross-tenant data access and host escape in github.com/daytonaio/daytona","description":"Daytona: Path traversal in sandbox volume id mounts arbitrary host paths into the sandbox — cross-tenant data access and host escape in github.com/daytonaio/daytona","state":0,"publishedAt":"2026-06-25T18:43:19+00:00","modifiedAt":"2026-06-25T19:45:19.1145558+00:00","affected":[{"ecosystem":"Go","name":"github.com/daytonaio/daytona","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.186.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/daytonaio/daytona/security/advisories/GHSA-fjv8-j4p5-cr9m"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-5367","license":"OSV · upstream source license applies","key":"osv:GO-2026-5367","identifiers":["GO-2026-5367","CVE-2026-54319","GHSA-fjv8-j4p5-cr9m"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
