Description

Improper signature counter value handling

Impact

A flaw was found in webauthn4j-spring-security-core. When an authneticator returns an incremented signature counter value during authentication, webauthn4j-spring-security-core does not properly persist the value, which means cloned authenticator detection does not work.
An attacker who cloned valid authenticator in some way can use the cloned authenticator without being detected.

Patches

Please upgrade to com.webauthn4j:webauthn4j-spring-security-core:0.9.1.RELEASE
