{"id":"ALPINE-CVE-2023-23969","details":"In Django 3.2 before 3.2.17, 4.0 before 4.0.9, and 4.1 before 4.1.6, the parsed values of Accept-Language headers are cached in order to avoid repetitive parsing. This leads to a potential denial-of-service vector via excessive memory usage if the raw value of Accept-Language headers is very large.","modified":"2026-11-03T06:32:48.024294891Z","published":"2023-02-01T19:15:08.763Z","upstream":["CVE-2023-23969"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-23969"}],"affected":[{"package":{"name":"py3-django","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}},{"package":{"name":"py3-django","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}},{"package":{"name":"py3-django","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}},{"package":{"name":"py3-django","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}},{"package":{"name":"py3-django","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}},{"package":{"name":"py3-django","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}},{"package":{"name":"py3-django","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}},{"package":{"name":"py3-django","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/py3-django?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-23969.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
