CVE-2026-100605: Missing Authorization in FlowiseAI Flowise
CVE-2026-100605 is a vulnerability in FlowiseAI's Flowise product up to version 3.1.4. It involves missing route-level role-based access control (RBAC) checks on chat message API endpoints. This flaw allows attackers with valid but low-privileged API keys to read and delete chat histories, including prompts and model responses, without having the necessary permissions.
AI Analysis
Technical Summary
Flowise versions up to and including 3.1.4 have a missing authorization vulnerability on chat message endpoints. Specifically, low-privileged API keys can access GET and DELETE routes for chat messages without proper flow permissions. This enables unauthorized reading and deletion of chat histories, prompts, and model responses, violating intended access controls.
Potential Impact
Attackers possessing valid but low-privileged API keys can bypass intended access restrictions to read sensitive chat histories and delete messages. This compromises confidentiality and integrity of chat data within Flowise, potentially exposing sensitive information and allowing unauthorized data modification.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict issuance of API keys to trusted users only and monitor API key usage closely to detect unauthorized access attempts.
