Description

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity low, availability none.
