SCA: security update for fastapi (GHSA-8h2j-cgx8-6xv7)

high Tenable Self-Hosted Container Security Plugin ID 412682

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- FastAPI is a web framework for building APIs with Python 3.6+ based on standard Python type hints. FastAPI
versions lower than 0.65.2 that used cookies for authentication in path operations that received JSON
payloads sent by browsers were vulnerable to a Cross-Site Request Forgery (CSRF) attack. In versions lower
than 0.65.2, FastAPI would try to read the request payload as JSON even if the content-type header sent
was not set to application/json or a compatible JSON media type (e.g. application/geo+json). A request
with a content type of text/plain containing JSON data would be accepted and the JSON data would be
extracted. Requests with content type text/plain are exempt from CORS preflights, for being considered
Simple requests. The browser will execute them right away including cookies, and the text content could be
a JSON string that would be parsed and accepted by the FastAPI application. This is fixed in FastAPI
0.65.2. The request data is now parsed as JSON only if the content-type header is application/json or
another JSON compatible media type like application/geo+json. It's best to upgrade to the latest FastAPI,
but if updating is not possible then a middleware or a dependency that checks the content-type header and
aborts the request if it is not application/json or another JSON compatible content type can act as a
mitigating workaround. (CVE-2021-32677)
