# Django 3.2.11 release notes

*January 4, 2022*

Django 3.2.11 fixes one security issue with severity “medium” and two security
issues with severity “low” in 3.2.10.

## CVE-2021-45115: Denial-of-service possibility in `UserAttributeSimilarityValidator`

[`UserAttributeSimilarityValidator`](/pt-br/5.2/topics/auth/passwords/#django.contrib.auth.password_validation.UserAttributeSimilarityValidator) incurred significant overhead
evaluating submitted password that were artificially large in relative to the
comparison values. On the assumption that access to user registration was
unrestricted this provided a potential vector for a denial-of-service attack.

In order to mitigate this issue, relatively long values are now ignored by
`UserAttributeSimilarityValidator`.

This issue has severity “medium” according to the [Django security policy](/pt-br/5.2/internals/security/#severity-levels).

## CVE-2021-45116: Potential information disclosure in `dictsort` template filter

Due to leveraging the Django Template Language’s variable resolution logic, the
[`dictsort`](/pt-br/5.2/ref/templates/builtins/#std-templatefilter-dictsort) template filter was potentially vulnerable to information
disclosure or unintended method calls, if passed a suitably crafted key.

In order to avoid this possibility, `dictsort` now works with a restricted
resolution logic, that will not call methods, nor allow indexing on
dictionaries.

As a reminder, all untrusted user input should be validated before use.

This issue has severity “low” according to the [Django security policy](/pt-br/5.2/internals/security/#severity-levels).

## CVE-2021-45452: Potential directory-traversal via `Storage.save()`

`Storage.save()` allowed directory-traversal if directly passed suitably
crafted file names.

This issue has severity “low” according to the [Django security policy](/pt-br/5.2/internals/security/#severity-levels).
