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."},{"lang":"es","value":"Una vulnerabilidad en corydolphin/flask-cors versión 4.0.1 permite coincidencias CORS inconsistentes debido a la gestión del carácter \"+\" en las rutas URL. El archivo request.path se pasa a través de la función unquote_plus, que convierte el carácter \"+\" en un espacio. Este comportamiento provoca una normalización incorrecta de las rutas, lo que puede provocar discrepancias en la configuración CORS.
