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.

GHSA-wp74-f5hh-5f3r — Flowise: Missing authorization on `/api/v1/files` allows low-privileged API keys to list and delete files across worksp…

Affected: npm: flowise

# summary: In Flowise, the `/api/v1/files` route is protected only by the `feat:files` feature gate and does not enforce `checkPermission(...)` on either `GET` or `DELETE`. As a result, any authenticated API key within the organization, even one with unrelated permissions, can list and delete files belonging to other workspaces in the same organization.

# details: The `/files` route is mounted with `IdentityManager.checkFeatureByPlan('feat:files')` only and has no additional permission middleware. In the controller:

- `getAllFiles` uses only `req.user.activeOrganizationId` and calls `getFilesListFromStorage(activeOrganizationId)`, which recursively lists files under the organization storage root - `deleteFile` reads `activeWorkspaceId`, but only uses it for storage quota bookkeeping; the actual deletion is performed using `activeOrganizationId + user-controlled path`

As a result, the API key’s `permissions` and `activeWorkspaceId` are not used to restrict file access. In the local test environment,an API key bound to workspace `1592b32a-a11b-4996-80b6-e1c4c2969d88` with only `["tools:view"]` was created, then successfully:

- called `GET /api/v1/files` and received `200 OK` - listed a test file stored under a different workspace, `f92a9a4d-392e-4db2-af82-d14e1d553446` - called `DELETE /api/v1/files?path=f92a9a4d-392e-4db2-af82-d14e1d553446/poc-cross-workspace.txt` and received `200 OK` - confirmed the file was removed by re-querying the file list

WID-SEC-W-2026-2589 — Flowise: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen in Flowise ausnutzen, um beliebigen Code auszuführen – sogar mit Root-Rechten –, erweiterte Privilegien zu erlangen, Sicherheitsmaßnahmen zu umgehen, Sitzungen zu kapern sowie Daten offenzulegen oder zu manipulieren.
