What it is

CyberPanel versions 2.4.3 through 2.4.5 expose unauthenticated AI Scanner debugging endpoints that disclose administrator usernames, API-key prefixes, scan identifiers, target domains, and account metadata. Unauthenticated attackers can enumerate panel administrators and recent scanner activity to inventory multi-tenant installations and facilitate follow-on attacks.
