Werkzeug is a Web Server Gateway Interface web application library. Applications
using `werkzeug.formparser.MultiPartParser` corresponding to a version of Werkzeug
prior to 3.0.6 to parse `multipart/form-data` requests (e.g. all flask applications)
are vulnerable to a relatively simple but effective resource exhaustion (denial of
service) attack. A specifically crafted form submission request can cause the parser
to allocate and block 3 to 8 times the upload size in main memory. There is no upper
limit; a single upload at 1 Gbit/s can exhaust 32 GB of RAM in less than 60 seconds.
Werkzeug version 3.0.6 fixes this issue.
