CVE-2026-91932

HighCVSS 8.5
Published: Updated: Translated: NVD NIST

Summary

Flowise before 3.1.4 contains a validation bypass in MCP server configuration allowing an authenticated attacker to achieve remote code execution through an unvalidated cwd parameter. The attacker can bypass path validation using clean filenames in the args array while controlling the working directory.

Risk Assessment

An authenticated attacker can execute arbitrary code on the Flowise server, leading to full system compromise and loss of confidentiality, integrity, and availability.

Recommendation

Upgrade Flowise to version 3.1.4 or later. Restrict permissions of accounts able to configure MCP servers and verify cwd parameter validation.
