Summary
laravel-auth0 SDK Deserialization of Untrusted Data vulnerability
Details

Overview The laravel-auth0 SDK contains a critical vulnerability due to insecure deserialization of cookie data. If exploited, since SDKs process cookie content without prior authentication, a threat actor could send a specially crafted cookie containing malicious serialized data.

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

  1. Applications using laravel-auth0 SDK, versions between 7.0.0-BETA1 to 7.2.1.
  2. Laravel-auth0 SDK uses the Auth0-PHP SDK with version 8.0.0-BETA3 to 8.3.0.

Fix Upgrade Auth0/laravel-auth0 to the latest version (v7.17.0).

Acknowledgement Okta would like to thank Andreas Forsblom for discovering this vulnerability.
