An operator's `executor_config` reaches that branch, so a Dag author could place a value there that causes an arbitrary callable to be imported and invoked -- for example `subprocess.check_output`, or `builtins.eval` on the `builtins`-prefixed variant. The code runs in the **Scheduler**, which reconstructs serialized Dags in its normal loop with no request involved, and in the **API server**, on any authenticated read of the Dag such as `GET /api/v2/dags/{dag_id}/details`. Both are components the Airflow security model states must never execute Dag-author code, and both hold the metadata database credentials and the JWT signing secret. No non-default configuration is required. This is a **different sink from CVE-2026-33264**, which covered only the trigger branch of the same deserializer: deployments that upgraded in response to that advisory are still affected through the exception branch and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later, which restricts the imported class to a subclass of `BaseException`."}],"affected":[{"source":"security@apache.org","affectedData":[{"vendor":"Apache Software Foundation","product":"Apache Airflow","defaultStatus":"unaffected","collectionURL":"https://pypi.python.org","packageName":"apache-airflow","versions":[{"version":"3.0.0","lessThan":"3.3.1","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-08-18T13:43:21.351742Z","id":"CVE-2026-58076","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@apache.org","type":"Secondary","description":[{"lang":"en","value":"CWE-502"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3.0","versionEndExcluding":"3.3.1","matchCriteriaId":"F6D5F0B2-15A2-4782-8CC5-769E57D5F2F6"}]}]}],"references":[{"url":"https://github.com/apache/airflow/pull/68511","source":"security@apache.org","tags":["Issue Tracking","Patch"]},{"url":"https://lists.apache.org/thread/t81p688t15jozxsng8521o60nh2kfsos","source":"security@apache.org","tags":["Mailing List","Vendor Advisory"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-33264","source":"security@apache.org","tags":["Not Applicable"]}]}}]}
