CVE-2025-64459: Django vulnerable to SQL injection via _connector keyword argument in QuerySet and Q objects.
An issue was discovered in 5.1 before 5.1.14, 4.2 before 4.2.26, and 5.2 before 5.2.8. The methods QuerySet.filter(), QuerySet.exclude(), and QuerySet.get(), and the class Q(), are subject to SQL injection when using a suitably crafted dictionary, with dictionary expansion, as the connector argument. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
