# Catatan terbitan Django 1.4.20

*18 Maret 2015*

Django 1.4.20 memperbaiki masalah keamanan di 1.4.19.

## Mengurangi kemungkinan serangan XSS melalui mengalihkan URL penyediaan-pengguna

Django relies on user input in some cases (e.g.
`django.contrib.auth.views.login()` and [i18n](/id/4.0/topics/i18n/))
to redirect the user to an "on success" URL. The security checks for these
redirects (namely `django.utils.http.is_safe_url()`) accepted URLs with
leading control characters and so considered URLs like `\x08javascript:...`
safe. This issue doesn't affect Django currently, since we only put this URL
into the `Location` response header and browsers seem to ignore JavaScript
there. Browsers we tested also treat URLs prefixed with control characters such
as `%08//example.com` as relative paths so redirection to an unsafe target
isn't a problem either.

Bagaimanapun, jika seorang pengembang bergantung pada `is_safe_url()` untuk menyediakan ssaran pengalihan aman dan menaruh URL itu kedalam sebuah tautan, mereka dapat menderita dari sebuah serangan XSS ketika beberapa peramban seperti Google Chrome mengabaikan kendali karakter pada awal dari URL di sebuah jangkar `href`.
