Sources and claim methodology

  • Source referencevulncheck.com
Upstream source description

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.
