CVE-2026-87820
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.
Does this matter?
Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.
Description
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.
