{"id":"PYSEC-2023-246","details":"aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel). These bugs have been addressed in commit `d5c12ba89` which has been included in release version 3.8.6. Users are advised to upgrade. There are no known workarounds for these issues.","aliases":["CVE-2023-47627","GHSA-gfw2-4jvh-wgfg"],"modified":"2023-11-22T23:41:28.136683Z","published":"2023-11-14T21:15:00Z","references":[{"type":"ADVISORY","url":"https://github.com/aio-libs/aiohttp/security/advisories/GHSA-gfw2-4jvh-wgfg"},{"type":"FIX","url":"https://github.com/aio-libs/aiohttp/commit/d5c12ba890557a575c313bb3017910d7616fce3d"}],"affected":[{"package":{"name":"aiohttp","ecosystem":"PyPI","purl":"pkg:pypi/aiohttp"},"ranges":[{"type":"GIT","repo":"https://github.com/aio-libs/aiohttp","events":[{"introduced":"0"},{"fixed":"d5c12ba890557a575c313bb3017910d7616fce3d"}]},{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8.6"}]}],"versions":["0.1","0.10.0","0.10.1","0.10.2","0.11.0","0.12.0","0.13.0","0.13.1","0.14.0","0.14.1","0.14.2","0.14.3","0.14.4","0.15.0","0.15.1","0.15.2","0.15.3","0.16.0","0.16.1","0.16.2","0.16.3","0.16.4","0.16.5","0.16.6","0.17.0","0.17.1","0.17.2","0.17.3","0.17.4","0.18.0","0.18.1","0.18.2","0.18.3","0.18.4","0.19.0","0.2","0.20.0","0.20.1","0.20.2","0.21.0","0.21.1","0.21.2","0.21.4","0.21.5","0.21.6","0.22.0","0.22.0a0","0.22.0b0","0.22.0b1","0.22.0b2","0.22.0b3","0.22.0b4","0.22.0b5","0.22.0b6","0.22.1","0.22.2","0.22.3","0.22.4","0.22.5","0.3","0.4","0.4.1","0.4.2","0.4.3","0.4.4","0.5.0","0.6.0","0.6.1","0.6.2","0.6.3","0.6.4","0.6.5","0.7.0","0.7.1","0.7.2","0.7.3","0.8.0","0.8.1","0.8.2","0.8.3","0.8.4","0.9.0","0.9.1","0.9.2","0.9.3","1.0.0","1.0.1","1.0.2","1.0.3","1.0.5","1.1.0","1.1.1","1.1.2","1.1.3","1.1.4","1.1.5","1.1.6","1.2.0","1.3.0","1.3.1","1.3.2","1.3.3","1.3.4","1.3.5","2.0.0","2.0.0rc1","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.0.7","2.1.0","2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5","2.3.0","2.3.0a1","2.3.0a2","2.3.0a3","2.3.0a4","2.3.1","2.3.10","2.3.1a1","2.3.2","2.3.2b2","2.3.2b3","2.3.3","2.3.4","2.3.5","2.3.6","2.3.7","2.3.8","2.3.9","3.0.0","3.0.0b0","3.0.0b1","3.0.0b2","3.0.0b3","3.0.0b4","3.0.1","3.0.2","3.0.3","3.0.4","3.0.5","3.0.6","3.0.7","3.0.8","3.0.9","3.1.0","3.1.1","3.1.2","3.1.3","3.2.0","3.2.1","3.3.0","3.3.0a0","3.3.1","3.3.2","3.3.2a0","3.4.0","3.4.0a0","3.4.0a3","3.4.0b1","3.4.0b2","3.4.1","3.4.2","3.4.3","3.4.4","3.5.0","3.5.0a1","3.5.0b1","3.5.0b2","3.5.0b3","3.5.1","3.5.2","3.5.3","3.5.4","3.6.0","3.6.0a0","3.6.0a1","3.6.0a11","3.6.0a12","3.6.0a2","3.6.0a3","3.6.0a4","3.6.0a5","3.6.0a6","3.6.0a7","3.6.0a8","3.6.0a9","3.6.0b0","3.6.1","3.6.1b3","3.6.1b4","3.6.2","3.6.2a0","3.6.2a1","3.6.2a2","3.6.3","3.7.0","3.7.0b0","3.7.0b1","3.7.1","3.7.2","3.7.3","3.7.4","3.7.4.post0","3.8.0","3.8.0a7","3.8.0b0","3.8.1","3.8.2","3.8.3","3.8.4","3.8.5"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/aiohttp/PYSEC-2023-246.yaml"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
