Prior to version 0.16.0, a leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. This issue has been patched in version 0.16.0. Since exploitation requires the combination of buggy h11 with a buggy (reverse) proxy, fixing either component is sufficient to mitigate this issue. \nSeverity: 9.1 | CRITICAL \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"24 Apr 2025\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2025-04-24T23:06:10.000000Z"}, {"uuid": "d94c1d59-0812-4095-b2dd-4992970bd42a", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "af0120d0-3dac-4a6a-974b-a9f33d2a9846", "vulnerability": "CVE-2025-43859", "type": "not-exploited", "source": "https://github.com/MISP/misp-modules/issues/760", "content": "", "creation_timestamp": "2026-02-04T09:31:43.476650Z"}, {"uuid": "74fd12b0-d04a-489a-ad19-b4d2975ecceb", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2025-43859", "type": "seen", "source": "https://t.me/CyberBulletin/10685", "content": "\u26a1\ufe0fCVE-2025-43859: Request Smuggling Vulnerability in Python\u2019s h11 HTTP Library.\n\n#CyberBulletin", "creation_timestamp": "2025-04-27T03:34:22.000000Z"}, {"uuid": "b382da7a-2e6e-4dbf-b859-84d4b37bc2b6", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2025-43859", "type": "seen", "source": "https://t.me/CyberBulletin/3122", "content": "\u26a1\ufe0fCVE-2025-43859: Request Smuggling Vulnerability in Python\u2019s h11 HTTP Library.\n\n#CyberBulletin", "creation_timestamp": "2025-04-27T05:34:22.000000Z"}]}
