Potential Impact
An attacker without authentication can obtain email addresses of commenters via the onGetEmail endpoint. This exposure of personal information could lead to privacy violations or facilitate targeted phishing attacks. There is no indication of further system compromise or privilege escalation from this vulnerability.
Mitigation Recommendations
