CVE-2026-33034: CWE-770: Allocation of Resources Without Limits or Throttling in djangoproject Django
A vulnerability in Django versions 6. 0 before 6. 0. 4, 5. 2 before 5. 2. 13, and 4. 2 before 4. 2. 30 allows ASGI requests with missing or understated Content-Length headers to bypass the DATA_UPLOAD_MAX_MEMORY_SIZE limit.
AI Analysis
Technical Summary
CVE-2026-33034 is a resource allocation vulnerability (CWE-770) in Django web framework versions 6.0 (before 6.0.4), 5.2 (before 5.2.13), and 4.2 (before 4.2.30). The issue arises when ASGI requests omit or understate the Content-Length header, allowing attackers to bypass the configured DATA_UPLOAD_MAX_MEMORY_SIZE limit. This results in unbounded loading of request bodies into memory, which can exhaust server resources. Unsupported earlier versions such as 5.0.x, 4.1.x, and 3.2.x were not evaluated but may also be vulnerable. The vulnerability has a CVSS v3.1 score of 7.5 (high severity) with no confidentiality or integrity impact but a high impact on availability.
Potential Impact
The vulnerability can lead to denial of service by exhausting server memory through unbounded request body loading. There is no direct impact on confidentiality or integrity. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the official Django vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates. Until a fix is available, consider implementing request size validation at upstream proxies or web servers to limit request body sizes and prevent resource exhaustion.
