In accordance with our security release policy, the Django team is issuing Django 3.2.4, Django 3.1.12, and Django 2.2.24. These release addresses the security issue detailed below. We encourage all users of Django to upgrade as soon as possible.
Staff members could use the admindocs TemplateDetailView view to check the existence of arbitrary files. Additionally, if (and only if) the default admindocs templates have been customized by the developers to also expose the file contents, then not only the existence but also the file contents would have been exposed.
As a mitigation, path sanitation is now applied and only files within the template root directories can be loaded.
This issue has low severity, according to the Django security policy.
Thanks to Rasmus Lerchedahl Petersen and Rasmus Wriedt Larsen from the CodeQL Python team for the report.
URLValidator, validate_ipv4_address(), and validate_ipv46_address() didn’t prohibit leading zeros in octal literals. If you used such values you could suffer from indeterminate SSRF, RFI, and LFI attacks.
validate_ipv4_address() and validate_ipv46_address() validators were not affected on Python 3.9.5+.
This issue has medium severity, according to the Django security policy.

Django 3.2 alpha 1 is now available. It represents the first stage in the 3.2 release cycle and is an opportunity for you to try out the changes coming in Django 3.2.
Django 3.2 has a mezcla of new features which you can read about in the in-development 3.2 release notes.
This alpha milestone marks the feature freeze. The current release schedule calls for a beta release in about a month and a release candidate about a month from then. We’ll only be able to keep this schedule if we get early and often testing from the community. Updates on the release schedule are available on the django-developers mailing list.

Our Redis™ customers who have Lua scripts deployed often report this error – “BUSY Redis is busy running a script. You can only call SCRIPT KILL or SHUTDOWN NOSAVE”. In this post, we will explain the Redis transactional property of scripts, what this error is about, and why we must be extra careful about it on Sentinel-managed systems that can failover.
Redis “transactions” aren’t really transactions as understood conventionally – in case of errors, there is no rollback of writes made by the script.
“Atomicity” of Redis scripts is guaranteed in the following manner:
It is highly recommended that the script complete within a time limit. Redis enforces this in a weak manner with the ‘lua-time-limit’ value. This is the maximum allowed time (in ms) that the script is allowed to run. The default value is 5 seconds. This is a really long time for CPU-bound activity (scripts have limited access and can’t run commands that access the disk).
However, the script is not killed when it executes beyond this time. Redis starts accepting client commands again, but responds to them with a BUSY error.
If you must kill the script at this point, there are two options available:
It is usually better to just wait for the script to complete its operation. The complete information on methods to kill the script execution and related behavior are available in the documentation.
