Django Incorrect Default Permissions

An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). The intermediate-level directories of the filesystem cache had the system's standard umask rather than 0o077.

Django Directory Traversal via archive.extract

In Django 2.2 before 2.2.18, 3.0 before 3.0.12, and 3.1 before 3.1.6, the django.utils.archive.extract method (used by startapp --template and startproject --template) allows directory traversal via an archive with absolute paths or relative paths with dot segments.

Django Incorrect Default Permissions

An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). FILEUPLOADDIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories created in the process of uploading files. It was also not applied to intermediate-level collected static directories when using the collectstatic management command.

Django Access Control Bypass possibly leading to SSRF, RFI, and LFI attacks

In Django 2.2 before 2.2.24, 3.x before 3.1.12, and 3.2 before 3.2.4, URLValidator, validateipv4address, and validateipv46address do not prohibit leading zero characters in octal literals. This may allow a bypass of access control that is based on IP addresses. (validateipv4address and validateipv46address are unaffected with Python 3.9.5+..) .
