CVE-2025-57833 is a high-severity SQL injection vulnerability affecting multiple recent versions of the Django web framework, specifically versions 4.2 prior to 4.2.24, 5.1 prior to 5.1.12, and 5.2 prior to 5.2.6. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89) within the FilteredRelation feature. This feature allows developers to create filtered joins in Django ORM queries. The flaw is triggered when a specially crafted dictionary is passed as keyword arguments (**kwargs) to the QuerySet.annotate() or QuerySet.alias() methods, which internally use FilteredRelation. By exploiting this, an attacker can inject malicious SQL code into column aliases, potentially manipulating the underlying SQL query structure. The CVSS 3.1 base score is 7.1, indicating high severity, with the vector AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N. This means the attack can be performed remotely over the network but requires low privileges and high attack complexity, with no user interaction needed. The impact on confidentiality is high, as attackers may extract sensitive data, while integrity is moderately affected due to possible query manipulation. Availability is not impacted. The vulnerability affects the confidentiality and integrity of data managed by Django applications using the affected versions and the vulnerable ORM features. No known exploits are currently reported in the wild, but the presence of this vulnerability in a widely used web framework poses a significant risk if left unpatched. Organizations using Django in these versions should prioritize updating to patched releases as soon as they become available to mitigate potential exploitation.

For European organizations, the impact of CVE-2025-57833 can be substantial, especially for those relying on Django-based web applications handling sensitive or regulated data such as personal information, financial records, or intellectual property. Successful exploitation could lead to unauthorized data disclosure, violating GDPR and other data protection regulations, potentially resulting in legal penalties and reputational damage. The partial integrity compromise could allow attackers to manipulate query results, leading to incorrect application behavior or data corruption. Given Django's popularity in Europe among startups, SMEs, and large enterprises for rapid web development, many organizations could be exposed. Critical sectors such as finance, healthcare, government, and e-commerce are particularly at risk due to the sensitivity of their data and the regulatory environment. Additionally, the vulnerability's remote exploitation capability means attackers can target exposed web applications without needing local access, increasing the attack surface. The lack of user interaction requirement facilitates automated scanning and exploitation attempts. Although the attack complexity is high, skilled adversaries or state-sponsored actors could develop reliable exploits, especially as the vulnerability becomes publicly known. Therefore, European organizations must assess their Django deployments urgently and apply mitigations to prevent data breaches and maintain compliance.

1. Immediate upgrade: Organizations should upgrade Django to versions 4.2.24, 5.1.12, or 5.2.6 or later, where this vulnerability is patched. 2. Code audit: Review all uses of QuerySet.annotate() and QuerySet.alias() with dictionary expansions in the codebase to identify potentially vulnerable patterns. 3. Input validation: Implement strict validation and sanitization of any user-supplied data that could be passed as keyword arguments to these ORM methods to prevent injection vectors. 4. ORM usage best practices: Avoid dynamic construction of **kwargs for annotate() or alias() from untrusted sources. Prefer explicit field definitions and parameterized queries. 5. Monitoring and logging: Enhance logging around database query generation and monitor for anomalous query patterns that could indicate exploitation attempts. 6. Web application firewall (WAF): Deploy or update WAF rules to detect and block suspicious payloads targeting SQL injection in Django ORM calls. 7. Security testing: Incorporate automated security scanning tools that can detect SQL injection vulnerabilities in Django applications during development and deployment cycles. 8. Incident response preparedness: Prepare to respond to potential exploitation attempts by having forensic and remediation plans in place. These steps go beyond generic advice by focusing on the specific ORM methods and usage patterns implicated in this vulnerability.
