Details

### 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-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:
- a. Auth0/symfony,
- b. Auth0/laravel-auth0,
- c. Auth0/wordpress.
### Resolution
Upgrade Auth0/Auth0-PHP to version 8.18.0 or greater.
