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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-22"],"references":["https://github.com/dagu-org/dagu/commit/7d07fda8f9de3ae73dfb081ccd0639f8059c56bb","https://github.com/dagu-org/dagu/security/advisories/GHSA-ph8x-4jfv-v9v8"],"products":["dagu:dagu"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33344","score":0.00487,"percentile":0.41958,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-ph8x-4jfv-v9v8","url":"https://osv.dev/vulnerability/GHSA-ph8x-4jfv-v9v8","summary":"Dagu has an incomplete fix for CVE-2026-27598: path traversal via %2F-encoded slashes in locateDAG","modified":"2026-03-27T22:17:37.291596Z","packages":[{"ecosystem":"Go","name":"github.com/dagu-org/dagu","purl":"pkg:golang/github.com/dagu-org/dagu","ranges":[">=1.30.4-0.20260221021317-e2ed589105d7 <1.30.4-0.20260319093346-7d07fda8f9de"],"fixed":["1.30.4-0.20260319093346-7d07fda8f9de"]}]},{"id":"GO-2026-4785","url":"https://osv.dev/vulnerability/GO-2026-4785","summary":"Dagu has an incomplete fix for CVE-2026-27598: path traversal via %2F-encoded slashes in locateDAG in github.com/dagu-org/dagu","modified":"2026-03-23T18:45:20.786381Z","packages":[{"ecosystem":"Go","name":"github.com/dagu-org/dagu","purl":"pkg:golang/github.com/dagu-org/dagu","ranges":[">=1.30.4-0.20260221021317-e2ed589105d7 <1.30.4-0.20260319093346-7d07fda8f9de"],"fixed":["1.30.4-0.20260319093346-7d07fda8f9de"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
