{"id":"CVE-2026-15830","summary":"Potential denial-of-service vulnerability via nested geometry collections","details":"An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8.\nGeoDjango's `django.contrib.gis.geos.GEOSGeometry` is subject to a potential denial-of-service when parsing deeply nested `GEOMETRYCOLLECTION` objects supplied as well-known text (WKT), well-known binary (WKB), or hex-encoded WKB, which triggers unbounded recursion and a segmentation fault in the underlying GEOS library. Spatial field lookups and the `django.contrib.gis.forms.GeometryField` form field are also affected.\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 Andrew MacPherson and kimchunbok_ for reporting this issue.","aliases":["BIT-django-2026-15830","PYSEC-2026-3717"],"modified":"2026-08-20T03:31:25.052688912Z","published":"2026-08-04T15:48:34.075Z","related":["SUSE-SU-2026:3503-1","openSUSE-SU-2026:11464-1","openSUSE-SU-2026:11465-1","openSUSE-SU-2026:11491-1","openSUSE-SU-2026:21543-1"],"database_specific":{"cwe_ids":["CWE-674"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15830.json","cna_assigner":"DSF"},"references":[{"type":"WEB","url":"https://github.com/django/django/"},{"type":"ADVISORY","url":"https://docs.djangoproject.com/en/dev/releases/security/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15830.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15830"},{"type":"ADVISORY","url":"https://www.djangoproject.com/weblog/2026/aug/04/security-releases/"},{"type":"FIX","url":"https://github.com/django/django/commit/6af5da31775417c610dbf9c3f1b5b8333d42daf6"},{"type":"FIX","url":"https://github.com/django/django/commit/9e4a3f186b6b07b483bfd9195ea06734663fcd06"},{"type":"FIX","url":"https://github.com/django/django/commit/ba80833fa656dd09660b97c4429331067db1b080"},{"type":"FIX","url":"https://github.com/django/django/commit/d2e59b77fe18de318a8272c2a7bbc798d84d1d0d"},{"type":"PACKAGE","url":"https://pypi.org/project/Django/"},{"type":"ARTICLE","url":"https://groups.google.com/g/django-announce"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/django/django","events":[{"introduced":"36b5f39d9372147f0e758f590e35ee2b2bc317dd"},{"fixed":"b2821457e8bfa9e9066837b9f9b3a3955224ab19"},{"introduced":"9e7cc2b628fe8fd3895986af9b7fc9525034c1b0"},{"fixed":"e802ada38b3ecf345915163bb6d7f008be411664"}],"database_specific":{"extracted_events":[{"introduced":"6.0"},{"fixed":"6.0.8"},{"introduced":"5.2"},{"fixed":"5.2.17"}],"source":"AFFECTED_FIELD"}}],"versions":["5.2.16","6.0.7","5.2.15","6.0.6","5.2.14","6.0.5","5.2.13","6.0.4","5.2.12","6.0.3","5.2.11","6.0.2","6.0.1","5.2.10","6.0","5.2.9","5.2.8","5.2.7","5.2.6","5.2.5","5.2.4","5.2.3","5.2.2","5.2.1","5.2"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-15830.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
