source listed
  • ECOSYSTEM: introduced 5.0.0; fixed 5.6.0

### Description 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. ### Affected product and versions Projects are affected if they meet the following preconditions: - Applications using the Auth0 Symfony SDK with versions between 5.0.0 and 5.5.0 - Auth0 Symfony SDK uses the Auth0-PHP SDK with versions between 8.0.0 and 8.17.0. ### Resolution Upgrade Auth0/symfony to version 5.6.0 or greater. ### Acknowledgement Okta would like to thank Jafar Sadiq (iaf4r) for their discovery and responsible disclosure.

A fixed release is not deployment evidence.

Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
