What is CVE-2026-41473?

CyberPanel versions before 2.4.4 are exposed to an authentication bypass vulnerability that affects the AI Scanner worker API endpoints. This flaw enables unauthenticated remote attackers to gain unauthorized access and potentially write arbitrary data to the database. By manipulating requests sent to the /api/ai-scanner/status-webhook and /api/ai-scanner/callback endpoints, attackers can exploit the absence of proper authentication checks. This could result in denial of service through storage exhaustion, corruption of scan history records, and the injection of malicious data into database fields.

Exploit Proof of Concept (PoC)
