Prior to 0.83.39, a missing authorization directive on the GET /api/v1/stable/dags/tasks endpoint caused Hatchet's tenant-membership check to be skipped for this route. A user authenticated to any tenant on the same Hatchet instance could query the endpoint with another tenant's UUID and a DAG UUID belonging to that tenant, and receive task metadata for that DAG. This vulnerability is fixed in 0.83.39.","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:N/A:N","score":6.5},"cwes":["CWE-639","CWE-863"],"references":["https://github.com/hatchet-dev/hatchet/security/advisories/GHSA-55gc-6fmc-fpx9"],"products":["hatchet:hatchet"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-42572","score":0.00181,"percentile":0.07689,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-55gc-6fmc-fpx9","url":"https://osv.dev/vulnerability/GHSA-55gc-6fmc-fpx9","summary":"Hatchet affected by cross-tenant information disclosure in `listTasksByDAGIds`","modified":"2026-06-25T18:56:26.654747989Z","packages":[{"ecosystem":"Go","name":"github.com/hatchet-dev/hatchet","purl":"pkg:golang/github.com/hatchet-dev/hatchet","ranges":["<0.83.39"],"fixed":["0.83.39"]}]},{"id":"GO-2026-5134","url":"https://osv.dev/vulnerability/GO-2026-5134","summary":"Hatchet affected by cross-tenant information disclosure in `listTasksByDAGIds` in github.com/hatchet-dev/hatchet","modified":"2026-06-25T18:45:23.907548210Z","packages":[{"ecosystem":"Go","name":"github.com/hatchet-dev/hatchet","purl":"pkg:golang/github.com/hatchet-dev/hatchet","ranges":["<0.83.39"],"fixed":["0.83.39"]}]}],"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).
