CVE-2025-64458: Potential denial-of-service vulnerability in HttpResponseRedirect and HttpResponsePermanentRedirect on Windows¶
Python's NFKC normalization is slow on

HttpResponsePermanentRedirect, and the shortcut
redirect() were subject to a potential
denial-of-service attack via certain inputs with a very large number of Unicode
characters (follow up to CVE 2025-27556).

QuerySet.filter(), exclude(), get(),
and Q were subject to SQL injection using a suitably crafted
dictionary, with dictionary expansion, as the _connector argument.
