Path Equivalence Affecting python-flask-cors package, versions *

Note: Versions mentioned in the description apply only to the upstream python-flask-cors package and not the python-flask-cors package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

corydolphin/flask-cors version 4.0.1 contains an improper regex path matching vulnerability. The plugin prioritizes longer regex patterns over more specific ones when matching paths, which can lead to less restrictive CORS policies being applied to sensitive endpoints. This mismatch in regex pattern priority allows unauthorized cross-origin access to sensitive data or functionality, potentially exposing confidential information and increasing the risk of unauthorized actions by malicious actors.
