If you cannot patch yet, restrict access to the Plugin Daemon's internal REST API to trusted users only and monitor for suspicious activity involving path traversal patterns. Consider disabling or restricting debug interfaces if possible. Since unauthenticated free registration is allowed, implement additional controls such as rate limiting or tenant UUID protections to reduce attack surface.
Description
Dify version 1.14.1 and prior contain a path traversal vulnerability that allows authenticated users to manipulate requests forwarded to the Plugin Daemon's internal REST API by exploiting insufficient URL path sanitization. Attackers can traverse out of their authorized tenant path using unencoded dot sequences in task identifiers or manipulated filename parameters to access internal endpoints such as debug interfaces, requiring only knowledge of the victim tenant's UUID. NOTE: Dify Cloud allows unauthenticated free self-registration, making account creation trivially accessible to any attacker.
