{"id":"GHSA-m3px-q5gj-j9x7","summary":"kafka-python vulnerable to denial of service through an unvalidated protocol frame length","details":"kafka-python prior to 2.3.2 contains a denial-of-service vulnerability in the protocol parser that allows a malicious broker or machine-in-the-middle attacker to exhaust memory or hang connections by sending a crafted 4-byte frame length value without bounds validation. Attackers can send a specially crafted frame length through the receive_bytes() function to trigger either a multi-gigabyte memory allocation or an uncaught ValueError that leaves the connection in a broken state, causing requests to hang and consumers to stop heartbeating until restart.","aliases":["CVE-2026-10142","PYSEC-2026-2190"],"modified":"2026-09-10T03:51:08.925920927Z","published":"2026-06-11T00:32:04Z","database_specific":{"github_reviewed_at":"2026-09-01T17:15:36Z","nvd_published_at":"2026-06-10T22:16:55Z","cwe_ids":["CWE-789"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-10142"},{"type":"WEB","url":"https://github.com/dpkp/kafka-python/pull/3019"},{"type":"WEB","url":"https://github.com/dpkp/kafka-python/pull/3026"},{"type":"WEB","url":"https://github.com/dpkp/kafka-python/commit/6e4831444f972d169cdd11f5c8d50333cea3f19b"},{"type":"WEB","url":"https://github.com/dpkp/kafka-python/commit/9f92d0f53ecfee738c54638867c3d67f83017bca"},{"type":"PACKAGE","url":"https://github.com/dpkp/kafka-python"},{"type":"WEB","url":"https://github.com/dpkp/kafka-python/releases/tag/2.3.2"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/kafka-python/PYSEC-2026-2190.yaml"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/kafka-python-prior-to-denial-of-service-via-protocol-parser-frame-length"}],"affected":[{"package":{"name":"kafka-python","ecosystem":"PyPI","purl":"pkg:pypi/kafka-python"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3.2"}]}],"versions":["0.9.0","0.9.1","0.9.2","0.9.3","0.9.4","0.9.5","1.0.0","1.0.1","1.0.2","1.1.0","1.1.1","1.2.0","1.2.1","1.2.2","1.2.3","1.2.4","1.2.5","1.3.0","1.3.1","1.3.2","1.3.3","1.3.4","1.3.5","1.4.0","1.4.1","1.4.2","1.4.3","1.4.4","1.4.5","1.4.6","1.4.7","2.0.0","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5","2.1.6","2.2.0","2.2.1","2.2.10","2.2.11","2.2.12","2.2.13","2.2.14","2.2.15","2.2.16","2.2.17","2.2.18","2.2.19","2.2.2","2.2.20","2.2.3","2.2.4","2.2.5","2.2.6","2.2.7","2.2.8","2.2.9","2.3.0","2.3.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-m3px-q5gj-j9x7/GHSA-m3px-q5gj-j9x7.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:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
