Flowise versions before 3.1.4 contain cross-tenant authorization gaps in Enterprise endpoints that fail to verify resource ownership before operations. Attackers with Enterprise access can delete arbitrary workspaces, invite themselves into other organizations, modify cross-org roles, and abuse stored SSO secrets.

AnalysisAI

Cross-tenant authorization bypass in Flowise Enterprise endpoints (all versions before 3.1.4) allows an authenticated Enterprise user to operate on resources owned by other organizations — deleting arbitrary workspaces, inviting themselves into other tenants, modifying cross-organization roles, and reading or abusing stored SSO secrets. The root cause is CWE-862 (missing authorization): affected endpoints act on caller-supplied resource identifiers without verifying tenant ownership. …
