Because `SyncCallback` is itself an Airflow class it passes the default `allowed_deserialization_classes` allow-list, so tightening that setting does not help. A Dag author — who controls a task instance's `next_kwargs` through the task execution API — can therefore cause an arbitrary module to be imported inside the scheduler process, when the scheduler's `awaiting_input` timeout sweep deserializes that value. No non-default configuration is required; the sweep runs unconditionally. Versions before 3.3.0 are not affected: the class existed, but the scheduler sweep that reaches it did not. This is a separate code path from CVE-2026-58076 and CVE-2026-67260, which cover different gadgets reaching deserialization — applying either of those fixes does not address this one. 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: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":"2026-08-13T12:17:23.923988Z","id":"CVE-2026-67587","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/70704","source":"security@apache.org","tags":["Issue Tracking","Patch"]},{"url":"https://lists.apache.org/thread/o00ww4n69qojvsckb464dtwd2nhzy6t0","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"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-67260","source":"security@apache.org","tags":["Not Applicable"]}]}}]}
