CVE-2026-1207 Overview
CVE-2026-1207 is a SQL Injection vulnerability affecting Django, the popular Python web framework. The vulnerability exists in raster lookups on RasterField, which is only implemented on PostGIS. Remote attackers with low privileges can inject SQL commands via the band index parameter, potentially allowing unauthorized data access or manipulation.
Critical Impact
Authenticated attackers can exploit this SQL injection flaw to read or modify database contents through maliciously crafted band index parameters in PostGIS raster lookups.
Affected Products
- Django 6.0 before 6.0.2
- Django 5.2 before 5.2.11
- Django 4.2 before 4.2.28
- Unsupported Django series (5.0.x, 4.1.x, 3.2.x) may also be affected

Technical Details for CVE-2026-1207
Vulnerability Analysis
This SQL Injection vulnerability (CWE-89) affects Django applications that utilize PostGIS and the RasterField functionality. The flaw resides in how Django processes the band index parameter during raster lookups. When user-controlled input is passed to this parameter without proper sanitization, it allows attackers to inject arbitrary SQL statements into database queries.
The vulnerability requires network access and low-level authentication to exploit. While the attack complexity is low, successful exploitation can lead to unauthorized read and write access to database contents. Applications that do not use PostGIS or RasterField are not affected by this vulnerability.
Root Cause
The root cause is improper input validation and sanitization of the band index parameter in Django's RasterField lookup implementation. The parameter is directly incorporated into SQL queries without adequate escaping or parameterization, violating secure coding practices for database interactions.
Attack Vector
The attack vector is network-based, requiring an authenticated attacker to craft malicious requests containing SQL payloads within the band index parameter. When the Django application processes raster lookups using PostGIS, the injected SQL is executed against the database.
The vulnerability can be exploited by manipulating the band index parameter in raster field queries. An attacker with valid credentials can craft malicious input that, instead of providing a legitimate numeric band index value, contains SQL commands that will be interpreted and executed by the database server. This allows reading sensitive data from other tables or potentially modifying database contents depending on database permissions. For detailed technical information, refer to the Django Security Release Documentation.
Detection Methods for CVE-2026-1207
Indicators of Compromise
- Unusual or malformed band index parameters in application logs containing SQL syntax
- Database query logs showing unexpected SQL statements within raster lookup operations
- Error messages revealing SQL injection attempts in PostGIS raster queries
- Anomalous database access patterns from authenticated user sessions
Detection Strategies
- Monitor web application logs for suspicious patterns in raster field query parameters
- Implement database query logging and alert on SQL syntax appearing in parameter values
- Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns
- Review application code for any custom implementations using RasterField lookups
Monitoring Recommendations
- Enable verbose logging for Django database operations in staging/testing environments
- Configure intrusion detection systems to flag SQL injection signature patterns
- Set up alerts for database errors related to malformed queries in PostGIS operations
- Audit authenticated user activities involving geographic/raster data access
How to Mitigate CVE-2026-1207
Immediate Actions Required
- Upgrade Django to patched versions: 6.0.2, 5.2.11, or 4.2.28 immediately
- If running unsupported Django versions (5.0.x, 4.1.x, 3.2.x), upgrade to a supported release
- Review application logs for any exploitation attempts prior to patching
- Conduct a security review of any custom code utilizing RasterField functionality
Patch Information
Django has released security patches addressing this vulnerability. Organizations should update to the following versions:
| Current Version | Update To |
|---|---|
| 6.0.x | 6.0.2 |
| 5.2.x | 5.2.11 |
| 4.2.x | 4.2.28 |
For detailed patch information, see the Django Weblog Security Releases Update.
Workarounds
- Temporarily disable raster field functionality if not critical to application operations
- Implement additional input validation on any user-controlled parameters used in raster lookups
- Apply network-level restrictions to limit access to affected endpoints
- Consider using a Web Application Firewall to filter malicious SQL injection patterns
# Upgrade Django to patched version
pip install --upgrade django==6.0.2
# Or for other supported versions:
# pip install --upgrade django==5.2.11
# pip install --upgrade django==4.2.28
# Verify installation
python -c "import django; print(django.VERSION)"
