{"id":"CVE-2024-52304","summary":"aiohttp vulnerable to request smuggling due to incorrect parsing of chunk extensions","details":"aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.10.11, the Python parser parses newlines in chunk extensions incorrectly which can lead to request smuggling vulnerabilities under certain conditions. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or `AIOHTTP_NO_EXTENSIONS` is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.10.11 fixes the issue.","aliases":["GHSA-8495-4g3g-x7pr"],"modified":"2026-04-16T04:40:19.228203629Z","published":"2024-11-18T20:12:48.612Z","related":["CGA-xhpq-xjpc-gfgp","SUSE-SU-2024:4077-1","SUSE-SU-2024:4110-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/52xxx/CVE-2024-52304.json","cwe_ids":["CWE-444"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/02/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/52xxx/CVE-2024-52304.json"},{"type":"ADVISORY","url":"https://github.com/aio-libs/aiohttp/security/advisories/GHSA-8495-4g3g-x7pr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-52304"},{"type":"FIX","url":"https://github.com/aio-libs/aiohttp/commit/259edc369075de63e6f3a4eaade058c62af0df71"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/aio-libs/aiohttp","events":[{"introduced":"0"},{"fixed":"3e09325e4839117df13fbac301f360edf8d3a0ee"}]}],"versions":["0.15.2","0.8.2","1.3.0","2.0.0","2.0.0rc1","4v0.21.6","v.0.6.5","v0.1","v0.10.0","v0.10.1","v0.11.0","v0.12.0","v0.13.0","v0.13.1","v0.14.0","v0.14.1","v0.14.2","v0.14.3","v0.14.4","v0.15.0","v0.15.1","v0.15.2","v0.15.3","v0.16.0","v0.16.1","v0.16.2","v0.16.3","v0.17.0","v0.18.0","v0.19.0","v0.2","v0.20.0","v0.20.1","v0.21.0","v0.22.0","v0.22.0b0","v0.22.0b1","v0.22.0b2","v0.22.0b3","v0.22.0b4","v0.22.0b5","v0.22.0b6","v0.22.1","v0.3","v0.4","v0.4.1","v0.4.2","v0.5.0","v0.6.1","v0.6.2","v0.6.3","v0.6.4","v0.7.0","v0.7.1","v0.7.2","v0.7.3","v0.8.0","v0.8.1","v0.8.3","v0.8.4","v0.9.0","v0.9.1","v0.9.2","v1.0.0","v1.0.1","v1.1.0","v1.1.1","v1.2.0","v2.1.0","v2.2.0","v2.3.0","v2.3.0a1","v2.3.0a2","v2.3.0a3","v2.3.0a4","v3.0.0b0","v3.0.0b1","v3.0.0b2","v3.0.0b3","v3.0.0b4","v3.1.0","v3.10.0","v3.10.0b0","v3.10.0b1","v3.10.0rc0","v3.10.1","v3.10.10","v3.10.11rc0","v3.10.2","v3.10.3","v3.10.4","v3.10.5","v3.10.6","v3.10.6rc0","v3.10.6rc1","v3.10.6rc2","v3.10.7","v3.10.8","v3.10.9","v3.2.0","v3.4.0","v3.4.0a0","v3.4.0a3","v3.4.0b1","v3.4.0b2","v3.5.0","v3.5.0a1","v3.5.0b1","v3.5.0b2","v3.5.0b3","v3.5.1","v3.5.2","v3.5.3","v3.5.4","v3.6.0","v3.6.0a0","v3.6.0a1","v3.6.0a10","v3.6.0a11","v3.6.0a12","v3.6.0a2","v3.6.0a3","v3.6.0a4","v3.6.0a5","v3.6.0a6","v3.6.0a7","v3.6.0a8","v3.6.0a9","v3.6.0b0","v3.6.1","v3.6.1b3","v3.6.1b4","v3.6.2","v3.6.2a1","v3.6.2a2","v3.7.0","v3.7.0b0","v3.7.0b1","v3.7.1","v3.8.0","v3.9.0","v3.9.0b0","v3.9.0b1","v3.9.0rc0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-52304.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
