{"id":"DEBIAN-CVE-2024-27306","details":"aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade.","modified":"2026-09-15T09:02:56.135256750Z","published":"2024-04-18T15:15:29.050Z","upstream":["CVE-2024-27306"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-27306"}],"affected":[{"package":{"name":"python-aiohttp","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-aiohttp?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.10.0-1","3.10.1-1","3.10.10-1","3.10.10-2","3.10.11-1","3.10.3-1","3.10.3-2","3.10.3-3","3.10.4-1","3.10.5-1","3.10.6-1","3.10.8-1","3.11.15-1","3.11.16-1","3.12.15-1","3.13.0-1","3.13.1-1","3.13.3-1","3.13.3-2","3.13.3-3","3.13.5-1","3.14.0-1","3.14.1-1","3.14.1-2","3.14.1-3","3.14.1-4","3.14.1-5","3.14.3-1","3.8.4-1","3.8.4-1+deb12u1","3.8.5-1","3.8.6-1","3.9.1-1","3.9.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-27306.json"}},{"package":{"name":"python-aiohttp","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-aiohttp?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-27306.json"}},{"package":{"name":"python-aiohttp","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-aiohttp?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-27306.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
