From version 2.0.0 to before version 2.3.1, the fix for CVE-2026-27598 added ValidateDAGName to CreateNewDAG and rewrote generateFilePath to use filepath.Base. This patched the CREATE path. The remaining API endpoints - GET, DELETE, RENAME, EXECUTE - all pass the {fileName} URL path parameter to locateDAG without calling ValidateDAGName. %2F-encoded forward slashes in the {fileName} segment traverse outside the DAGs directory. This issue has been patched in version 2.3.1.","published":"2026-03-24T19:23:56.617Z","modified":"2026-08-27T03:57:12.989406785Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/dagu-org/dagu","fixedVersion":"1.30.4-0.20260319093346-7d07fda8f9de"}],"fix":{"url":"https://github.com/dagu-org/dagu/commit/7d07fda8f9de3ae73dfb081ccd0639f8059c56bb","label":"dagu-org/dagu@7d07fda"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33344.json"},{"type":"ADVISORY","url":"https://github.com/dagu-org/dagu/security/advisories/GHSA-ph8x-4jfv-v9v8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33344"},{"type":"FIX","url":"https://github.com/dagu-org/dagu/commit/7d07fda8f9de3ae73dfb081ccd0639f8059c56bb"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:57:12.989406785Z"}}
