Exposing email addresses can lead to phishing attacks, spam, or social engineering attacks targeting the affected individuals.

If these emails are linked to privileged accounts (e.g., administrative roles or GitHub contributors), this exposure increases the risk of further exploitation, such as impersonation or unauthorized account access.
