SCA: security update for flask-cors (GHSA-8vgw-p6qm-5gr7)

medium Tenable Cloud Security Plugin ID 427720

Description

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

 - A vulnerability in corydolphin/flask-cors version 4.0.1 allows for inconsistent CORS matching due to the
 handling of the '+' character in URL paths. The request.path is passed through the unquote_plus function,
 which converts the '+' character to a space ' '. This behavior leads to incorrect path normalization,
 causing potential mismatches in CORS configuration. As a result, endpoints may not be matched correctly to
 their CORS settings, leading to unexpected CORS policy application. This can cause unauthorized cross-
 origin access or block valid requests, creating security vulnerabilities and usability issues.
 (CVE-2024-6844)
