Description
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.
