Django security releases issued: 5.2.2, 5.1.10, and 4.2.22
Posted by Natalia Bidart on 4 juin 2025

In accordance with our security release policy, the Django team is
issuing releases for Django 5.2.2, Django 5.1.10, and Django 4.2.22.
These releases address the security issues detailed below. We
encourage all users of Django to upgrade as soon as possible.


CVE-2025-48432: Potential log injection via unescaped request path

Internal HTTP response logging used request.path directly, allowing
control characters (e.g. newlines or ANSI escape sequences) to be
written unescaped into logs. This could enable log injection or
forgery, letting attackers manipulate log appearance or structure,
especially in logs processed by external systems or viewed in
terminals.

Although this does not directly impact Django's security model, it
poses risks when logs are consumed or interpreted by other tools.
To fix this, the internal django.utils.log.log_response() function
now escapes all positional formatting arguments using a safe
encoding.

Thanks to Seokchan Yoon (https://ch4n3.kr/) for the report.

This issue has severity "low" according to the Django security
policy.
