# CVE-2025-64459: Potential SQL injection via _connector keyword argument in QuerySet and Q objects

- Exploited (CISA KEV): no
- Published: 2025-11-05
- CVSS: 9.1 CRITICAL (v3.1)
- EPSS: 19.3% (97th percentile)
- CWE: CWE-89

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.
Django would like to thank cyberstan for reporting this issue.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
