AI-suggested
European organizations should immediately audit their use of Auth0-PHP SDK and related dependent SDKs/plugins to identify affected versions. The primary mitigation is to upgrade to Auth0-PHP version 8.18.0 or later, which contains the patch for proper audience validation. For dependent SDKs, upgrade to versions that incorporate the fixed Auth0-PHP SDK or apply vendor-recommended patches. Additionally, organizations should review their token validation logic to ensure strict enforcement of token types and audience claims, implementing defense-in-depth. Employ runtime monitoring and anomaly detection to identify suspicious token usage patterns that could indicate exploitation attempts. Conduct penetration testing focused on authentication flows to verify that ID tokens cannot be misused as access tokens. Finally, update incident response plans to address potential unauthorized access scenarios stemming from token validation issues.
Description
Auth0-PHP is a PHP SDK for Auth0 Authentication and Management APIs. In applications built with the Auth0-PHP SDK, the audience validation in access tokens is performed improperly. Without proper validation, affected applications may accept ID tokens as Access tokens. Projects are affected if they use Auth0-PHP SDK versions between v8.0.0 and v8.17.0, or applications using the following SDKs that rely on the Auth0-PHP SDK versions between v8.0.0 and v8.17.0: Auth0/symfony versions between 5.0.0 and 5.5.0, Auth0/laravel-auth0 versions between 7.0.0 and 7.19.0, and/or Auth0/wordpress plugin versions between 5.0.0-BETA0 and 5.4.0. Auth0/Auth0-PHP version 8.18.0 contains a patch for the issue.
