# Django 5.2.1 release notes

May 7, 2025

Django 5.2.1 fixes a security issue with severity “moderate” and several bugs in 5.2.

This release was built using an upgraded setuptools, producing filenames compliant with PEP 491 and PEP 625 and thus addressing a PyPI warning about non-compliant distribution filenames. This change only affects the Django packaging process and does not impact Django’s behavior.

## CVE-2025-32873: Denial-of-service possibility in `strip_tags()`

`strip_tags()` would be slow to evaluate certain inputs containing large sequences of incomplete HTML tags. This function is used to implement the `striptags` template filter, which was thus also vulnerable.

`strip_tags()` now raises a `SuspiciousOperation` exception if it encounters an unusually large number of unclosed opening tags.
