Cross-Site Scripting (XSS) in Cyberpanel (CVE-2026-41472)
Summary
Cross-site scripting in Cyberpanel (CVE-2026-41472). Risk of unauthorized operations or information disclosure. Exploitable via POST /api/ai-scanner/callback.
Original description
The description as published by the source.
CyberPanel versions prior to 2.4.4 contain a stored cross-site scripting vulnerability in the AI Scanner dashboard where the POST /api/ai-scanner/callback endpoint lacks authentication and allows unauthenticated attackers to inject malicious JavaScript by overwriting the findings_json field of ScanHistory records. Attackers can inject JavaScript that executes in an administrator's authenticated session when they visit the AI Scanner dashboard, allowing them to issue same-origin requests to plant cron jobs and achieve remote code execution on the server.

Attack vector: remote (network-reachable) / unauthenticated
Attack surface: POST /api/ai-scanner/callback
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
Cross-site scripting (XSS) (CWE-79) exists in Cyberpanel. Attackers reach the vulnerable code path via POST /api/ai-scanner/callback without authentication.
Check the vendor advisory for the affected versions of Cyberpanel. Attack surface: POST /api/ai-scanner/callback.
Severity: Medium (CVSS 6.1/10). Risk of unauthorized operations or information disclosure.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual POST /api/ai-scanner/callback requests with malformed payloads or SQL meta-characters. Run grep -r 'Cyberpanel' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

-
1Identify exposure identify
grep -r 'Cyberpanel' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
Cyberpanelを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'POST /api/ai-scanner/callback' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
POST /api/ai-scanner/callbackへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Post-deployment verification verify
Replay attack against POST /api/ai-scanner/callback on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
