CVE-2026-54206Public exploitNetwork attack vectorHinoki check available

Credential exposure via unvalidated UNC include path

Published Aug 7, 2026 · Updated Aug 7, 2026

SSRF in TeamDavid WebBox through Rollout 524 allows remote authenticated users to expose NetNTLM material through a crafted message. The message-sending handler resolves an unvalidated UNC path supplied to the @@INCLUDE command and initiates an outbound SMB connection. Exploitation requires message-sending access and permitted outbound TCP port 445; the resulting authentication can support credential theft or SMB relay.
