The vulnerability arises only when the validate_assertion_signature option is explicitly set to false, which is not the default configuration. Therefore, ensuring this option remains enabled (the default) mitigates the risk. Users should verify their configuration to confirm that validate_assertion_signature is not disabled.
Description
A SAML authentication bypass vulnerability affects the Kong SAML plugin when the validate_assertion_signature option is explicitly set to false. This option is enabled by default. When disabled, the plugin may extract the SAML identity from an unsigned assertion and authenticate the user without verifying a valid cryptographic signature. As a result, an unauthenticated remote attacker may be able to submit a crafted SAML response and impersonate arbitrary users, including administrators
