Echo: flask-cors: security update to 6.0.0

high Tenable Cloud Security Plugin ID 463710

Description

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

 - corydolphin/flask-cors version 4.01 contains a vulnerability where the request path matching is case-
 insensitive due to the use of the `try_match` function, which is originally intended for matching hosts.
 This results in a mismatch because paths in URLs are case-sensitive, but the regex matching treats them as
 case-insensitive. This misconfiguration can lead to significant security vulnerabilities, allowing
 unauthorized origins to access paths meant to be restricted, resulting in data exposure and potential data
 leaks. (CVE-2024-6866)

Solution

Update the flask-cors library and its related packages to version 6.0.0 or later.
