{"cve":"CVE-2026-15337","nvd":{"published":"2026-08-04T17:16:46.453","modified":"2026-10-24T16:10:00.153","status":"Analyzed","description":"An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8.\n`django.utils.translation.check_for_language()` is subject to a potential denial-of-service attack when given many distinct, very long language codes, which are retained as keys in an in-memory cache and consume process memory. Such codes reach the function through the `django.views.i18n.set_language()` view, which is not routed by default. The consumed memory is bounded, since request data is limited by the `DATA_UPLOAD_MAX_MEMORY_SIZE` setting (default 2.5 MB) and the cache holds a fixed maximum number of entries.\nEarlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected.\nDjango would like to thank Jaeyoung Jang for reporting this issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-789"],"references":["https://docs.djangoproject.com/en/dev/releases/security/","https://github.com/django/django/commit/224dbc832586ad5cfb0237c2ff30d14baeaddc6f","https://github.com/django/django/commit/27137e655e442e81095f1f8f77ff3870d9fdf169","https://github.com/django/django/commit/5b3523d29be25948e1dd90b3863a002f00fc865f","https://github.com/django/django/commit/c72a5dbb64d0777f3f471f1be94e8b2ca91e0959"],"products":["djangoproject:django"],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-15337","score":0.0059,"percentile":0.47913,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
