CVE-2026-30823Public exploitNetwork attack vector

Account takeover via unchecked SSO organization identifier

Published Mar 7, 2026 · Updated Mar 7, 2026

Authorization bypass in FlowiseAI Flowise before 3.0.13 allows remote authenticated users to take over accounts through SSO configuration. The PUT /api/v1/loginmethod handler trusts a body-supplied organizationId and updates that organization's SSO record without verifying ownership or administrative rights. A low-privileged account and a target organization identifier are required; successful requests can replace OAuth settings and redirect the victim's authentication flow.
