Archive of security issues¶
Django’s development team is strongly committed to responsible reporting and disclosure of security-related issues, as outlined in Django’s security policies.
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 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 prior to Django’s security process¶
Some security issues were handled before Django had a formalized security process in use. For these, new releases may not have been issued at the time and CVEs may not have been assigned.
