CVE-2024-7487Network attack vector

Unauthenticated authentication bypass via disabled attestation context

Published May 22, 2025 · Updated May 22, 2025

Improper authentication in WSO2 Identity Server 7.0.0 allows remote attackers to bypass app-native client attestation. ClientAttestationServiceImpl initializes the validation context with attestation disabled before handling an unrecognized attestation object, causing authorization endpoints to treat the check as disabled. The flaw requires an app configured for client attestation but no credentials or user interaction, and its reported impact is limited to authentication integrity.
