Additionally, if (and only if) the default admindocs templates have been customized by the developers to also expose the file contents, then not only the existence but also the file contents would have been exposed. As a mitigation, path sanitation is now applied and only files within the template root directories can be loaded. This issue has low severity, according to the Django security policy. Thanks to Rasmus Lerchedahl Petersen and Rasmus Wriedt Larsen from the CodeQL Python team for the report. * CVE-2021-33571: Possible indeterminate SSRF, RFI, and LFI attacks since validators accepted leading zeros in IPv4 addresses 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+. This issue has medium severity, according to the Django security policy. For Debian 9 "Stretch", this problem has been fixed in version 1:1.10.7-2+deb9u14. We recommend that you upgrade your python-django packages.
