CVE-2026-41473: CyberPanel < 2.4.5 Unauthenticated API Access via AI Scanner Endpoints

Noroxi assessment

Priority: Monitor (action score 35/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.79% (FIRST EPSS); higher than 56.3% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: usmannasir cyberpanel 2.4.5.

Low priority for now. Upgrade to usmannasir cyberpanel 2.4.5 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

CyberPanel versions prior to 2.4.5 contain an authentication bypass vulnerability in the AI Scanner worker API endpoints that allows unauthenticated remote attackers to write arbitrary data to the database by sending requests to the /api/ai-scanner/status-webhook and /api/ai-scanner/callback endpoints. Attackers can exploit the lack of authentication checks to cause denial of service through storage exhaustion, corrupt scan history records, and pollute database fields with malicious data.
