Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The auth0/login package (laravel-auth0 SDK) versions from 7.0.0-BETA1 before 7.2.2 are affected by insecure deserialization of cookie data. An unauthenticated attacker can send a specially crafted cookie containing malicious serialized data, and the source does not state the resulting impact. Upgrade auth0/login to version 7.2.2 or later.
