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.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-674"],"vendors":[],"products":[],"references":[{"url":"https://docs.djangoproject.com/en/dev/releases/security/","tags":[]},{"url":"https://github.com/django/django/commit/6af5da31775417c610dbf9c3f1b5b8333d42daf6","tags":[]},{"url":"https://github.com/django/django/commit/9e4a3f186b6b07b483bfd9195ea06734663fcd06","tags":[]},{"url":"https://github.com/django/django/commit/ba80833fa656dd09660b97c4429331067db1b080","tags":[]},{"url":"https://github.com/django/django/commit/d2e59b77fe18de318a8272c2a7bbc798d84d1d0d","tags":[]},{"url":"https://groups.google.com/g/django-announce","tags":[]},{"url":"https://www.djangoproject.com/weblog/2026/aug/04/security-releases/","tags":[]}],"exploitRefs":[{"url":"https://github.com/django/django/commit/6af5da31775417c610dbf9c3f1b5b8333d42daf6","tags":[]},{"url":"https://github.com/django/django/commit/9e4a3f186b6b07b483bfd9195ea06734663fcd06","tags":[]},{"url":"https://github.com/django/django/commit/ba80833fa656dd09660b97c4429331067db1b080","tags":[]},{"url":"https://github.com/django/django/commit/d2e59b77fe18de318a8272c2a7bbc798d84d1d0d","tags":[]}],"hasPoc":true,"ai":null}
