In Django 2.2 before 2.2.24, 3.x before 3.1.12, and 3.2 before 3.2.4,
URLValidator, validate_ipv4_address, and validate_ipv46_address do not
prohibit leading zero characters in octal literals. This may allow a bypass
of access control that is based on IP addresses. (validate_ipv4_address and
validate_ipv46_address are unaffected with Python 3.9.5+…) .

| mdeslaur | Python earlier than 3.8.0 is not vulnerable to CVE-2021-29921, so django in bionic and earlier do not require fixes |
