From 3.6.4 until 3.18.2, JSONParser.parse in rest_framework/parsers.py uses the client-supplied Content-Type charset value with codecs.getreader, which accepts byte-transform codecs such as bz2_codec rather than only text encodings. A remote unauthenticated client can therefore cause a compressed JSON request body to be expanded after Django has enforced DATA_UPLOAD_MAX_MEMORY_SIZE against only the wire bytes, allowing a very small request to consume substantial per-worker memory. The default parser set is sufficient, and any reachable endpoint that accepts a JSON body is affected. This issue is fixed in version 3.18.2.","score":7.5,"severity":"high","published":"2026-10-21T20:02:41.030Z","modified":"2026-10-30T19:24:46.203Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"encode","name":"django-rest-framework","platforms":[],"versions":[{"version":">= 3.6.4, < 3.18.2","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-114136"}],"remediation":[],"references":["https://github.com/encode/django-rest-framework/security/advisories/GHSA-3547-9m27-7rxg","https://github.com/encode/django-rest-framework/commit/3c2634599b26a9f789b03045118dbc276117611a","https://github.com/encode/django-rest-framework/releases/tag/3.18.2"],"sources":[{"name":"CVE","id":"CVE-2026-114136","modified":"2026-10-30T19:24:46.203Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-114136"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5}],"sourceAffected":[],"observedAt":"2026-10-30T19:39:30.736Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T07:10:30.687Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-30T19:45:34.093Z","attemptedAt":"2026-10-30T19:45:34.093Z"},{"source":"GHSA","status":"available","checkedAt":"2026-10-30T19:45:33.839Z","attemptedAt":"2026-10-30T19:45:33.839Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-30T19:45:33.398Z","attemptedAt":"2026-10-30T19:45:33.398Z"},{"source":"EPSS","status":"available","checkedAt":"2026-10-30T19:45:34.305Z","attemptedAt":"2026-10-30T19:45:34.305Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-107546","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-107546","modified":"Oct 21, 2026, 8:02:41 PM","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T19:45:33.398Z"},{"source":"GitHub Advisory Database","id":"GHSA-3547-9m27-7rxg","url":"https://github.com/advisories/GHSA-3547-9m27-7rxg","modified":"2026-10-22T16:16:56Z","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T19:45:33.839Z"},{"source":"NVD","id":"CVE-2026-114136","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114136","modified":"2026-10-22T17:21:57.293","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T19:45:34.093Z"},{"source":"FIRST EPSS","id":"CVE-2026-114136","url":"https://www.first.org/epss/","probability":0.00503,"percentile":0.43041,"date":"2026-10-30","checkedAt":"2026-10-30T19:45:34.305Z"}],"aiSummary":{"text":"Django REST framework versions 3.6.4 to 3.18.2 have a weakness where an unauthenticated client can cause a small JSON request to consume substantial memory.
