GHSA-35g6-rrw3-v6xc · Severity: high · Ecosystem: npm — FlowiseAI/Flosise has File Upload vulnerability
Flowise is a drag & drop user interface to build a customized large language model flow. A file upload vulnerability in version 3.0.7 of FlowiseAI allows authenticated users to upload arbitrary files without proper validation. This enables attackers to persistently store malicious Node.js web shells on the server, potentially leading to Remote Code Execution (RCE). The system fails to validate file extensions, MIME types, or file content during uploads. As a result, malicious scripts such as Node.js-based web shells can be uploaded and stored persistently on the server. These shells expose HTTP endpoints capable of executing arbitrary commands if triggered. The uploaded shell does not automatically execute, but its presence allows future exploitation via administrator error or chained vulnerabilities. This presents a high-severity threat to system integrity and confidentiality. As of time of publication, no known patched versions are available.
Conclusion & alert: CVE-2025-61687 is rated High Exploit Risk (86.5/100): CVSS High severity, with high exploitation likelihood (EPSS 10.18%, 95th percentile). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +9.82% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
