# Django 2.0.8 release notes

August 1, 2018

Django 2.0.8 fixes a security issue and several bugs in 2.0.7.

## CVE-2018-14574: Open redirect possibility in `CommonMiddleware`

If the `CommonMiddleware` and the `APPEND_SLASH` setting are both enabled, and if the project has a URL pattern that accepts any path ending in a slash (many content management systems have such a pattern), then a request to a maliciously crafted URL of that site could lead to a redirect to another site, enabling phishing and other attacks.

`CommonMiddleware` now escapes leading slashes to prevent redirects to other domains.

## Poprawki błędów

- Fixed a regression in Django 2.0.7 that broke the `regex` lookup on MariaDB (even though MariaDB isn’t officially supported) (#29544).
- Fixed a regression where `django.template.Template` crashed if the `template_string` argument is lazy (#29617).
