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:
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.
