"value": "Authentik is an open-source Identity Provider. There is a bug in our implementation of PKCE that allows an attacker to circumvent the protection that PKCE offers. PKCE adds the code_challenge parameter to the authorization request and adds the code_verifier parameter to the token request. Prior to 2023.8.7 and 2023.10.7, a downgrade scenario is possible: if the attacker removes the code_challenge parameter from the authorization request, authentik will not do the PKCE check. Because of this bug, an attacker can circumvent the protection PKCE offers, such as CSRF attacks and code injection attacks. Versions 2023.8.7 and 2023.10.7 fix the issue."

PKCE agrega el par\u00e1metro code_challenge a la solicitud de autorizaci\u00f3n y agrega el par\u00e1metro code_verifier a la solicitud de token. Antes de 2023.8.7 y 2023.10.7, es posible un escenario de degradaci\u00f3n: si el atacante elimina el par\u00e1metro code_challenge de la solicitud de autorizaci\u00f3n, authentik no realizar\u00e1 la verificaci\u00f3n PKCE. Debido a este error, un atacante puede eludir la protecci\u00f3n que ofrece PKCE, como los ataques CSRF y los ataques de inyecci\u00f3n de c\u00f3digo. Las versiones 2023.8.7 y 2023.10.7 solucionan el problema."
