In lunary-ai/lunary versions <=v1.2.11, an attacker can bypass email validation by using a dot character ('.') in the email address. This allows the creation of multiple accounts with essentially the same email address (e.g., '[email protected]' and '[email protected]'), leading to incorrect synchronization and potential security issues.
