CVE-2026-87820: Exposure of Sensitive Information to an Unauthorized Actor in usmannasir cyberpanel
CyberPanel versions 2.4.3 through 2.4.5 contain unauthenticated AI Scanner debugging endpoints that expose sensitive information such as administrator usernames, API-key prefixes, scan identifiers, target domains, and account metadata. This vulnerability allows unauthenticated attackers to enumerate panel administrators and recent scanner activity, potentially aiding further attacks on multi-tenant installations.
AI Analysis
Technical Summary
CVE-2026-87820 affects CyberPanel versions 2.4.3 through 2.4.5 by exposing unauthenticated AI Scanner debugging endpoints. These endpoints disclose sensitive information including administrator usernames, API-key prefixes, scan identifiers, target domains, and account metadata. The exposure enables attackers without authentication to enumerate administrators and scanner activity, which could facilitate follow-on attacks in environments where multiple tenants are hosted.
Potential Impact
The vulnerability allows unauthenticated attackers to access sensitive information that should be restricted, such as administrator usernames and API-key prefixes. This information disclosure can aid attackers in mapping the environment and planning further attacks. However, there is no indication of direct system compromise or code execution from this vulnerability alone.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to debugging endpoints and monitor for unauthorized access attempts if possible.
