{"id":"GHSA-fh37-cx83-q542","summary":"Improper Authentication in Apache Airflow","details":"The lineage endpoint of the deprecated Experimental API was not protected by authentication in Airflow 2.0.0. This allowed unauthenticated users to hit that endpoint. This is low-severity issue as the attacker needs to be aware of certain parameters to pass to that endpoint and even after can just get some metadata about a DAG and a Task. This issue only affects Apache Airflow 2.0.0.","aliases":["BIT-airflow-2021-26697","CVE-2021-26697","PYSEC-2021-3"],"modified":"2024-09-12T20:10:22Z","published":"2021-06-18T18:30:11Z","database_specific":{"github_reviewed_at":"2021-05-07T21:48:45Z","nvd_published_at":"2021-02-17T15:15:00Z","cwe_ids":["CWE-269","CWE-287","CWE-306"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-26697"},{"type":"WEB","url":"https://github.com/apache/airflow/commit/21cedff205e7d62675949fda2aa4616d77232b76"},{"type":"WEB","url":"https://github.com/apache/airflow/commit/24a54242d56058846c7978130b3f37ca045d5142"},{"type":"WEB","url":"https://github.com/apache/airflow/commit/93957e917ff4cfb0be11aef088bd9527cf728a04"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-fh37-cx83-q542"},{"type":"PACKAGE","url":"https://github.com/apache/airflow"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/apache-airflow/PYSEC-2021-3.yaml"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r36111262a59219a3e2704c71e97cf84937dae5ba7a1da99499e5d8f9@%3Cannounce.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re21fec81baea7a6d73b0b5d31efd07cc02c61f832e297f65bb19b519%40%3Cusers.airflow.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re21fec81baea7a6d73b0b5d31efd07cc02c61f832e297f65bb19b519@%3Cdev.airflow.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re21fec81baea7a6d73b0b5d31efd07cc02c61f832e297f65bb19b519@%3Cusers.airflow.apache.org%3E"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2021/02/17/2"}],"affected":[{"package":{"name":"apache-airflow","ecosystem":"PyPI","purl":"pkg:pypi/apache-airflow"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0"},{"fixed":"2.0.1rc1"}]}],"versions":["2.0.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/06/GHSA-fh37-cx83-q542/GHSA-fh37-cx83-q542.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
