{"id":"CVE-2020-15225","details":"django-filter is a generic system for filtering Django QuerySets based on user selections. In django-filter before version 2.4.0, automatically generated `NumberFilter` instances, whose value was later converted to an integer, were subject to potential DoS from maliciously input using exponential format with sufficiently large exponents. Version 2.4.0+ applies a `MaxValueValidator` with a a default `limit_value` of 1e50 to the form field used by `NumberFilter` instances. In addition, `NumberFilter` implements the new `get_max_validator()` which should return a configured validator instance to customise the limit, or else `None` to disable the additional validation. Users may manually apply an equivalent validator if they are not able to upgrade.","aliases":["GHSA-x7gm-rfgv-w973","PYSEC-2021-64"],"modified":"2026-04-10T04:22:51.430447Z","published":"2021-04-29T21:15:08.490Z","related":["GHSA-x7gm-rfgv-w973","MGASA-2021-0511"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DPHENTRHRAYFXYPPBT7JRHZRWILRY44S/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FAT2ZAEF6DM3VFSOHKB7X3ASSHGQHJAK/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVJ7AYU6FUSU3F653YCGW5LFD3IULRSX/"},{"type":"ADVISORY","url":"https://github.com/carltongibson/django-filter/security/advisories/GHSA-x7gm-rfgv-w973"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210604-0010/"},{"type":"ADVISORY","url":"https://github.com/carltongibson/django-filter/releases/tag/2.4.0"},{"type":"FIX","url":"https://github.com/carltongibson/django-filter/commit/340cf7a23a2b3dcd7183f6a0d6c383e85b130d2b"},{"type":"PACKAGE","url":"https://pypi.org/project/django-filter/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/carltongibson/django-filter","events":[{"introduced":"0"},{"fixed":"78210722d920f803a8142e48969bc37f0f8324ed"},{"fixed":"340cf7a23a2b3dcd7183f6a0d6c383e85b130d2b"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2.4.0"}]}}],"versions":["0.1.0","0.11.0","0.12.0","0.14.0","0.15.0","0.15.1","0.15.2","0.15.3","0.2.0","0.5.0","0.5.1","0.5.2","0.5.3","0.5.4","0.9.0","0.9.1","1.0.0","1.0.1","1.0.2","1.0.4","1.1.0","2.0.0","2.1.0","2.2.0","2.3.0","v0.10.0","v0.13","v0.6","v0.6a1","v0.7","v0.8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-15225.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"34"}]},{"events":[{"introduced":"0"},{"last_affected":"35"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
