CVE-2026-41948
CWE-23Published: May 18, 2026· Updated: May 19, 2026
Official 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.
Risk Analysis
This critical path traversal vulnerability in Dify allows authenticated users to access internal REST API endpoints. By manipulating URL paths with unencoded dot sequences, attackers can bypass authorization and access sensitive interfaces. With a CVSS score of 9.4, this is a serious concern, especially since Dify Cloud allows easy account creation.
No public exploit is currently known for this vulnerability. The flaw is remotely exploitable and requires authentication, though Dify Cloud's free self-registration makes obtaining credentials trivial.
Upgrade Dify to a version beyond 1.14.1 to address the path traversal vulnerability. Implement robust input validation and URL path sanitization to prevent traversal attacks.
Technical Analysis
CVE-2026-41948 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 9.4.
