NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2021-33571
Title: Django Server-Side Request Forgery (SSRF) Vulnerability
Overview:

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..) .
