CORS Misconfiguration in Flowise Allows Arbitrary Origins to Access Sensitive Information

CVE-2024-36421

What is CVE-2024-36421?

In Flowise version 1.4.3, a CORS misconfiguration allows the Access-Control-Allow-Origin header to accept requests from any origin. This vulnerability poses a significant risk as unauthenticated users can potentially make requests to the application, enabling them to steal sensitive information from users. Furthermore, this misconfiguration can be exploited alongside path injection techniques, allowing attackers without direct access to Flowise to read arbitrary files stored on the server. Current knowledge indicates that no patches are available to address this issue at the time of reporting.
