Critical Django Vulnerabilities Expose Applications to SQL Injection and DoS Attacks

February 21, 20262 min read

The Django Software Foundation has released emergency security updates to address six serious vulnerabilities affecting multiple supported versions of the Django web framework.

Several of the flaws allow SQL injection and denial-of-service (DoS) attacks, posing immediate risk to production applications that rely on Django for database-driven functionality.

Given Django’s widespread adoption across high-profile platforms, these vulnerabilities represent a material application security risk for organizations that have not yet applied patches.


🧩 Why This Matters

Django powers some of the world’s most heavily trafficked applications, including Instagram, Mozilla, and Bitbucket. Its rapid development model and database abstraction layers make it popular — but also attractive to attackers when flaws emerge.

On February 3, 2026, Django released patched versions:

  • Django 6.0.2

  • Django 5.2.11

  • Django 4.2.28

All supported versions are affected, and immediate upgrades are strongly recommended.


🔥 High-Severity SQL Injection Risks

Three vulnerabilities were rated high severity due to their ability to enable SQL injection under common development patterns.

⚠️ CVE-2026-1207 — PostGIS Raster SQL Injection

This flaw affects GIS raster lookups when untrusted input is used as a band index.

Applications leveraging PostGIS raster functionality may inadvertently allow attackers to inject SQL commands into database queries, leading to data exposure or manipulation.

⚠️ CVE-2026-1287 — FilteredRelation Alias Injection

Improper handling of control characters in column aliases allows SQL injection when using FilteredRelation in combination with:

  • annotate()

  • aggregate()

  • values()

Crafted dictionaries passed into QuerySet operations can trigger this vulnerability.

⚠️ CVE-2026-1312 — order_by() Alias Injection

A related injection vector exists when column aliases containing periods are used with QuerySet.order_by() alongside FilteredRelation queries.

This flaw reinforces the danger of relying on unvalidated query composition logic in ORM-based frameworks.


🧨 Denial-of-Service Vulnerabilities

Two moderate-severity DoS flaws were also addressed.

🛑 CVE-2025-14550 — ASGI Header Processing

Django’s ASGIRequest handler improperly processes duplicate HTTP headers, allowing attackers to trigger super-linear computational overhead through repeated string concatenation.

While not a direct data breach risk, this vulnerability enables targeted service degradation, particularly in high-traffic ASGI deployments.


🛡️ What Organizations Should Do Now

Elliptic Systems strongly recommends the following actions:

✔️ Upgrade immediately to Django 6.0.2, 5.2.11, or 4.2.28
✔️ Audit ORM usage, especially FilteredRelation, order_by(), and GIS queries
✔️ Sanitize all untrusted input, even when using ORM abstractions
✔️ Monitor ASGI applications for abnormal request patterns or resource exhaustion
✔️ Test for injection paths in staging environments before redeployment

ORM frameworks reduce risk — they don’t eliminate it.


🔐 The Elliptic Systems Takeaway

These vulnerabilities highlight a recurring truth in application security:

Framework safety depends on update discipline and secure usage patterns.

SQL injection remains one of the most exploited attack vectors — even in modern frameworks — when input validation and patching lag behind.

Elliptic Systems helps organizations:

  • Identify exploitable ORM patterns

  • Secure Python web stacks

  • Implement AppSec testing and runtime protections
