{"apiVersion":"1.0","identifier":"CVE-2026-67260","description":"Apache Airflow 3.3.0 moved human-in-the-loop tasks from the triggerer to a new `awaiting_input` task state swept by the scheduler. 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.","publishedAt":"2026-08-12T16:17:14","lastModifiedAt":"2026-08-17T19:07:20","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-67260","cvssScore":7.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","epssProbability":0.00779,"riskScore":0.78,"affectedProduct":"Apache Airflow","affectedVersions":">=3.3.0,<3.3.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-67260","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-67260","en":"https://www.redsauce.net/en/cves/CVE-2026-67260","fr":"https://www.redsauce.net/fr/cves/CVE-2026-67260","pt":"https://www.redsauce.net/pt/cves/CVE-2026-67260","de":"https://www.redsauce.net/de/cves/CVE-2026-67260","sk":"https://www.redsauce.net/sk/cves/CVE-2026-67260","el":"https://www.redsauce.net/el/cves/CVE-2026-67260"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-67260"}}
