High (7.5) in corydolphin flask-cors. EPSS 0.7% chance of exploitation in the next 30 days. Fixed in flask-cors 4.0.2.
A vulnerability in corydolphin/flask-cors version 4.0.1 allows the `Access-Control-Allow-Private-Network` CORS header to be set to true by default. This behavior can expose private network resources to unauthorized external access, leading to significant security risks such as data breaches, unauthorized access to sensitive information, and potential network intrusions.
