Overview
Session cookies of applications using the Auth0-PHP SDK configured with CookieStore have authentication tags that can be brute forced, which may result in unauthorized access.

Am I Affected?
You are affected by this vulnerability if you meet the following pre-conditions:

Applications using the Auth0-PHP SDK, or the following SDKs that rely on the Auth0-PHP SDK:
a. Auth0/symfony,
b. Auth0/laravel-auth0,
c. Auth0/wordpress,
Session storage configured with CookieStore.

Fix
Upgrade Auth0/Auth0-PHP to v8.14.0. As an additional precautionary measure, we recommend rotating your cookie encryption keys. Note that once updated, any previous session cookies will be rejected.
