CVE-2022-45597Network attack vector

Disputed trust bypass via unvalidated SAML certificates

Published Mar 24, 2023 · Updated Jul 9, 2026

The CVE reports that improper certificate validation in ComponentSpace.Saml2 4.4.0 allows attackers to bypass application-layer SAML trust checks. The library checks configured X.509 certificate expiry by default but does not inherently perform chain and revocation validation during SAML XML signature processing. ComponentSpace disputes the security impact because these certificates are exchanged among trusted SAML entities, while browsers validate transport-layer TLS.
