## Description

Dify v1.9.1 is vulnerable to Insecure Permissions. An unauthenticated attacker can directly send HTTP GET requests to the /console/api/system-features endpoint without any authentication credentials or session tokens. The endpoint fails to implement proper authorization checks, allowing anonymous access to sensitive system configuration data.

## CrowdSec analysis

[CVE-2025-63387](https://euvd.enisa.europa.eu/vulnerability/CVE-2025-63387) is a vulnerability in Dify v1.9.1 that allows unauthenticated attackers to access sensitive system configuration data by exploiting insecure permissions on the /console/api/system-features endpoint. This flaw could be leveraged for reconnaissance or information disclosure attacks, potentially aiding further exploitation of the system.

CrowdSec has been tracking this vulnerability and its exploits since 7th of January 2026.

Data from the CrowdSec community indicates that exploitation of CVE-2025-63387 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations.
CrowdSec network telemetry also shows that exploitation of CVE-2025-63387 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit this vulnerability by sending unauthenticated requests to the `/console/api/system-features` endpoint, allowing them to access sensitive system configuration data without proper authorization checks.
