DESCRIPTION¶
FIDO API can be accessed using the username and the password of a user, due to the improper authentication in the FIDO Rest API.
IMPACT¶
This vulnerability only impacts authentication flows where the FIDO authenticator is used. Additionally, in order to leverage this vulnerability a malicious actor should have the valid username and password of the targeted victim.
