- 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 References For more details about WebAuthn signature counters, see WebAuthn specification 6.1.1.
