{"cve":"CVE-2026-41084","nvd":{"published":"2026-06-01T09:16:18.453","modified":"2026-07-21T19:10:00.107","status":"Analyzed","description":"A bug in Apache Airflow's bulk Task Instances API (`PATCH/DELETE /api/v2/dags/{dag_id}/dagRuns/{dag_run_id}/taskInstances`) evaluated authorization against the `dag_id` resolved from the URL path while operating on the `dag_id` / `dag_run_id` extracted from request-body entity fields. An authenticated UI/API user with edit permission on one Dag could mutate Task Instance state in any other Dag by keeping the authorized Dag's ID in the URL path and naming the target Dag's IDs in the request body entities. Affects deployments that rely on per-Dag edit-scope to keep Task Instance state isolated between teams. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-639"],"references":["https://github.com/apache/airflow/pull/64288","https://lists.apache.org/thread/w0hdcqfr71hf9rl1bwvpjs7q9yp1bldk","http://www.openwall.com/lists/oss-security/2026/05/31/7"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-41084","score":0.00476,"percentile":0.41108,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mxq5-f9c5-w4p5","url":"https://osv.dev/vulnerability/GHSA-mxq5-f9c5-w4p5","summary":"Apache Airflow Vulnerable to Authorization Bypass Through User-Controlled Key","modified":"2026-07-09T21:11:37.388117749Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.2.0 <3.2.2"],"fixed":["3.2.2"]}]},{"id":"PYSEC-2026-183","url":"https://osv.dev/vulnerability/PYSEC-2026-183","summary":"","modified":"2026-07-13T16:45:06.301690821Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.2.0 <3.2.2"],"fixed":["3.2.2"]}]}],"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).
