# Documentazione Django 6.0.7

# Note di rilascio di Django 3.2.4

2 Giugno 2021

Django 3.2.4 risolve due problemi di sicurezza e alcuni bug in 3.2.3.

## CVE-2021-33203: Potential directory traversal via `admindocs`

Staff members could use the `admindocs` `TemplateDetailView` view to check the existence of arbitrary files. 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.

## 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+.
