# Django 6.0.7 documentation

# Django 5.1.8 release notes

April 2, 2025

Django 5.1.8 fixes a security issue with severity “moderate” and several bugs in 5.1.7.

## CVE-2025-27556: Potential denial-of-service vulnerability in `LoginView`, `LogoutView`, and `set_language()` on Windows

Python’s `NFKC normalization` is slow on Windows. As a consequence, `LoginView`, `LogoutView`, and `set_language()` were subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters.

## Bugfixes

- Fixed a regression in Django 5.1.7 where the removal of the `single_object` parameter unintentionally altered the signature and return type of `LogEntryManager.log_actions()` (#36234).
