CVE-2026-18348: RAPID7 Velociraptor

Medium severity, CVSS 4.1. EPSS: 0.3% chance of exploitation in the next 30 days.

Missing authorization check in the upload_azure, upload_sftp, and upload_smb VQL plugins allows an authenticated analyst-role user can initiate attacker-controlled outbound network connections from the Velociraptor server, bypassing the NETWORK ACL permission boundary. This enables internal network reconnaissance via port oracle and potential data exfiltration to external endpoints.

Affected products

• RAPID7 Velociraptor: before 0.77.2 (fixed in 0.77.2)
