## Description

Werkzeug is a Web Server Gateway Interface web application library.Applications using `werkzeug.formparser.MultiPartParser` corresponding to aversion of Werkzeug prior to 3.0.6 to parse `multipart/form-data` requests(e.g. all flask applications) are vulnerable to a relatively simple buteffective resource exhaustion (denial of service) attack. A specificallycrafted form submission request can cause the parser to allocate and block3 to 8 times the upload size in main memory. There is no upper limit; asingle upload at 1 Gbit/s can exhaust 32 GB of RAM in less than 60 seconds.Werkzeug version 3.0.6 fixes this issue.
