From 0.101.0 until 0.184.0, sandbox previews that were switched from public to private could remain reachable without authentication for a short period after the change, due to a cached visibility state that was not invalidated when the sandbox's visibility changed. This vulnerability is fixed in 0.184.0.","published":"2026-06-23T18:10:05.521Z","modified":"2026-08-07T11:31:19.369084500Z","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L"},"epss":{"score":0.00249,"percentile":0.16186,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/daytonaio/daytona","fixedVersion":"0.184.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54321.json"},{"type":"ADVISORY","url":"https://github.com/daytonaio/daytona/security/advisories/GHSA-ww63-pv5x-vfc8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54321"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:19.369084500Z"}}
