Django 5.1.1 release notes

September 3, 2024

Django 5.1.1 fixes one security issue with severity "moderate", one security issue with severity "low", and several bugs in 5.1.

CVE-2024-45230: Potential denial-of-service vulnerability in django.utils.html.urlize()

urlize and urlizetrunc were subject to a potential denial-of-service attack via very large inputs with a specific sequence of characters.

CVE-2024-45231: Potential user email enumeration via response status on password reset

Due to unhandled email sending failures, the PasswordResetForm class allowed remote attackers to enumerate user emails by issuing password reset requests and observing the outcomes.

To mitigate this risk, exceptions occurring during password reset email sending are now handled and logged using the django.contrib.auth logger.

漏洞修复

• Fixed a regression in Django 5.1 that caused a crash of Window() when passing an empty sequence to the order_by parameter, and a crash of Prefetch() for a sliced queryset without ordering (#35665).

• Fixed a regression in Django 5.1 where a new usable_password field was included in BaseUserCreationForm (and children). A new AdminUserCreationForm including this field was added, isolating the feature to the admin where it was intended (#35678).

• Adjusted the deprecation warning stacklevel in Model.save() and Model.asave() to correctly point to the offending call site (#35060).

• Adjusted the deprecation warning stacklevel when using OS_OPEN_FLAGS in FileSystemStorage to correctly point to the offending call site (#35326).

• Adjusted the deprecation warning stacklevel in FieldCacheMixin.get_cache_name() to correctly point to the offending call site (#35405).

• Restored, following a regression in Django 5.1, the ability to override the timezone and role setting behavior used within the init_connection_state method of the PostgreSQL backend (#35688).

• Fixed a bug in Django 5.1 where variable lookup errors were logged when rendering admin fieldsets (#35716).
