That sweep deserializes the task instance's `next_kwargs` without an allow-list, so a Dag author — who controls that value through the task execution API — can cause an arbitrary module import and object instantiation inside the scheduler process, or terminate the scheduler job. No non-default configuration is required: the sweep runs unconditionally every 15 seconds, and the default `allowed_deserialization_classes` setting does not cover this code path. Versions before 3.3.0 are not affected, because human-in-the-loop tasks deferred onto the triggerer instead. This is a different code path from CVE-2026-58076, which covers the same unguarded exception-node deserialization reached elsewhere — deployments that applied that fix must upgrade for this issue as well. Users are advised to upgrade to apache-airflow 3.3.1 or later."}],"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":"3.3.0","lessThan":"3.3.1","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","baseScore":7.3,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":3.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-08-12T16:00:14.166719Z","id":"CVE-2026-67260","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"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/70685","source":"security@apache.org","tags":["Issue Tracking","Patch"]},{"url":"https://lists.apache.org/thread/vygr0fh82cjzjp5k4vtfmboxryvm3lyn","source":"security@apache.org","tags":["Mailing List","Vendor Advisory"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-58076","source":"security@apache.org","tags":["Not Applicable"]}]}}]}
