Dify Path Traversal (CVE-2026-41948) Allows Internal API Access
The National Vulnerability Database reports a high-severity path traversal vulnerability, CVE-2026-41948, affecting Dify versions 1.14.1 and earlier. This flaw allows authenticated users to manipulate requests forwarded to the Plugin Daemon’s internal REST API. The core issue lies in insufficient URL path sanitization, enabling attackers to bypass authorization boundaries.
Attackers can exploit this by using unencoded dot sequences in task identifiers or manipulated filename parameters. This allows them to traverse out of their authorized tenant path and access internal endpoints, including debug interfaces. Critically, only knowledge of the victim tenant’s UUID is required for exploitation. The National Vulnerability Database also highlights that Dify Cloud’s unauthenticated free self-registration makes account creation trivially accessible, significantly lowering the bar for attackers to gain initial authenticated access.
With a CVSS score of 7.7 (HIGH), this vulnerability presents a significant risk. The attacker’s calculus is straightforward: gain an account, identify a target tenant’s UUID (which can often be enumerated or inferred), and then leverage the path traversal to access sensitive internal APIs. This could lead to data exfiltration, service manipulation, or further compromise within the Dify environment.
What This Means For You
- If your organization uses Dify, particularly Dify Cloud, you need to prioritize patching to version 1.14.2 or newer immediately. Audit your Dify environments for any unusual API calls or access patterns, especially those involving the Plugin Daemon. Assume that if you haven't patched, you are exposed. This isn't just about data; it's about control over your AI application infrastructure.
