Package Instance

An issue was discovered in 5.2 before 5.2.9, 5.1 before 5.1.15, and 4.2 before 4.2.27.
`FilteredRelation` is subject to SQL injection in column aliases, using a suitably crafted dictionary, with dictionary expansion, as the `**kwargs` passed to `QuerySet.annotate()` or `QuerySet.alias()` on PostgreSQL.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank Stackered for reporting this issue.

Django vulnerable to Uncontrolled Resource Consumption
An issue was discovered in 6.0 before 6.0.3, 5.2 before 5.2.12, and 4.2 before 4.2.29.

`URLField.to_python()` in Django calls `urllib.parse.urlsplit()`, which performs NFKC normalization on Windows that is disproportionately slow for certain Unicode characters, allowing a remote attacker to cause denial of service via large URL inputs containing these characters.
