Vulnerability description
DayBreach CVE AI Research
CVE-2026-18348 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
