==========================
Archive of security issues
==========================

Django's development team is strongly committed to responsible
reporting and disclosure of security-related issues, as outlined in
:doc:`Django's security policies </internals/security>`.

As part of that commitment, we maintain the following historical list
of issues which have been fixed and disclosed. For each issue, the
list below includes the date, a brief description, the `CVE identifier
<https://en.wikipedia.org/wiki/Common_Vulnerabilities_and_Exposures>`_
if applicable, a list of affected versions, a link to the full
disclosure and links to the appropriate patch(es).

Some important caveats apply to this information:

* Lists of affected versions include only those versions of Django
  which had stable, security-supported releases at the time of
  disclosure. This means older versions (whose security support had
  expired) and versions which were in pre-release (alpha/beta/RC)
  states at the time of disclosure may have been affected, but are not
  listed.

* The Django project has on occasion issued security advisories,
  pointing out potential security problems which can arise from
  improper configuration or from other issues outside of Django
  itself. Some of these advisories have received CVEs; when that is
  the case, they are listed here, but as they have no accompanying
  patches or releases, only the description, disclosure and CVE will
  be listed.

Issues under Django's security process
======================================

All security issues have been handled under versions of Django's security
