Regular Expression Denial of Service (ReDoS)

fastapi is a web framework for building APIs with Python 3.6+ based on standard Python type hints.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the parsing of the HTTP Content-Type header when reading form data with python-multipart. An attacker can cause a denial of service by sending a specially crafted Content-Type header that leads to excessive CPU consumption and indefinite stalling of the main event loop, preventing the processing of further requests.

How to fix Regular Expression Denial of Service (ReDoS)?

Upgrade fastapi to version 0.109.1 or higher.
