{"id":"CVE-2026-33344","summary":"Dagu has an incomplete fix for CVE-2026-27598: path traversal via %2F-encoded slashes in locateDAG","details":"Dagu is a workflow engine with a built-in Web user interface. 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.","aliases":["GHSA-ph8x-4jfv-v9v8","GO-2026-4785"],"modified":"2026-04-02T13:27:22.390569Z","published":"2026-03-24T19:23:56.617Z","related":["SUSE-SU-2026:1135-1"],"database_specific":{"cwe_ids":["CWE-22"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33344.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33344.json"},{"type":"FIX","url":"https://github.com/dagu-org/dagu/commit/7d07fda8f9de3ae73dfb081ccd0639f8059c56bb"},{"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dagu-org/dagu","events":[{"introduced":"b5df396d90297479b625eb7c7a7494089ba931eb"},{"fixed":"b120a51bc2e236b2d7184058adad76a2324052b9"}],"database_specific":{"versions":[{"introduced":"2.0.0"},{"fixed":"2.3.1"}]}}],"versions":["helm-dagu-1.0.0","helm-dagu-1.0.1","helm-dagu-1.0.2","helm-dagu-1.0.4","v2.0.0","v2.0.1","v2.0.2","v2.0.3","v2.0.4","v2.0.5","v2.1.0","v2.1.1","v2.1.2","v2.1.3","v2.2.0","v2.2.1","v2.2.2","v2.2.3","v2.2.4","v2.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33344.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
