Hi, The following vulnerability was published for python-werkzeug. CVE-2024-49767[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
