CVE-2026-54206 is a server-side request forgery issue in Tobit Laboratories AG TeamDavid Webbox messaging functionality. The @@INCLUDE command accepts a pathname that can specify a UNC network location. TeamDavid processes the supplied UNC path without validating that it refers to an approved local resource, causing the server to initiate SMB authentication to an attacker-selected endpoint. The pathname parameter can be exploited without authentication. The issue affects TeamDavid releases before Rollout 528.

An unauthenticated UNC-path injection flaw in Tobit TeamDavid Webbox's @@INCLUDE pathname handling. It can force the server to connect and authenticate to arbitrary attacker-controlled SMB endpoints, potentially exposing NTLM authentication material and enabling SMB relay or credential-theft attacks when outbound SMB/445 is allowed.
A TeamDavid SSRF vulnerability via UNC paths in the authenticated move archive functionality, allowing outbound SMB connections to attacker-controlled hosts.
