CVE-2026-69252: Flowiseai Flowise

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the /api/v1/files route was protected only by the feat:files feature gate and did not enforce checkPermission on GET or DELETE. A low-privileged authenticated API key with unrelated permissions could call GET /api/v1/files to list files under the organization storage root and DELETE /api/v1/files?path=... to delete files belonging to other workspaces in the same organization because getAllFiles and deleteFile used activeOrganizationId and a user-controlled path without restricting access by permissions or activeWorkspaceId. This issue is fixed in version 3.1.3.

Affected products

• Flowiseai Flowise: before 3.1.3 (fixed in 3.1.3)
