CVE-2026-1287 is a medium-severity vulnerability found in specific versions of Django, namely 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28. This vulnerability allows for SQL injection in column aliases through control characters when using a specially crafted dictionary as parameters in certain QuerySet methods. Organizations utilizing these versions are at risk and must take action to mitigate potential exploitation.
The vulnerability was published on February 3, 2026. The risk to organizations includes unauthorized access to sensitive data and potential manipulation of the database. Given the nature of the vulnerability, it is essential for organizations to prioritize patching these affected versions to prevent exploitation.
Currently, there are no known exploits or public proofs of concept, which indicates a lower immediate risk. However, organizations should remain vigilant and proactive in applying updates. The Django development team has acknowledged the issue thanks to the report from Solomon Kebede.
Organizations should prioritize patching immediately. The urgency of remediation is critical, especially considering that earlier unsupported Django versions may also be affected.
Vulnerability Details
The official description of this vulnerability states that it involves SQL injection in the `FilteredRelation` component due to improper handling of control characters in column aliases. The vulnerability affects the following versions:
• Django 4.2 before 4.2.28 • Django 5.2 before 5.2.11 • Django 6.0 before 6.0.2
The CVSS score is 5.4, indicating a medium severity. The vulnerability is classified as CWE-89 (SQL Injection). It is important for organizations to understand the implications of this vulnerability and to act accordingly.
Technical Analysis
The root cause of this vulnerability stems from how Django's `FilteredRelation` processes column aliases using control characters. Attackers may leverage this flaw to execute arbitrary SQL commands by passing specially crafted dictionaries as `**kwargs` in certain QuerySet methods, such as `annotate()`, `aggregate()`, and others. The attack vector is through the network, and it requires low privileges and no user interaction, making it easier to exploit.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is significant. Organizations using affected versions of Django are exposed to SQL injection attacks that could lead to unauthorized data access or corruption. The blast radius is considerable, as many applications may rely on these vulnerable versions of Django, potentially affecting a large number of users. Given the CVSS score of 5.4, organizations should address this vulnerability in their priority patch cycle.
