Description
+ A security issue has been found in Django before version 3.2.4. URLValidator, validate_ipv4_address(), and validate_ipv46_address() didn't prohibit leading zeros in octal literals. If you used such values you could suffer from indeterminate SSRF, RFI, and LFI attacks. validate_ipv4_address() and validate_ipv46_address() validators were not affected on Python 3.9.5+.
