Description

Flowise: DELETE /api/v1/chatflows/:id does not validate resource type, allowing agentflows:delete and chatflows:delete to delete each other’s flow type

# summary:

In Flowise, DELETE /api/v1/chatflows/:id authorizes requests with checkAnyPermission('chatflows:delete,agentflows:delete'). Possession of either permission is sufficient to reach the delete path. The delete logic does not validate the target resource type, allowing a caller with only agentflows:delete to delete a CHATFLOW, and a caller with only chatflows:delete to delete an AGENTFLOW.

# details:

The delete route accepts either chatflows:delete or agentflows:delete. The subsequent logic only resolves the target record by id and workspaceId, then deletes by id without checking whether the target resource type matches the granted permission domain.

As a result, there is no binding between permission scope and flow type:

  • agentflows:delete can be used to delete CHATFLOW
  • chatflows:delete can be used to delete AGENTFLOW

This breaks the intended RBAC separation between Chatflows and Agentflows.

# impact:

Users authorized to manage only one flow type can delete the other flow type within the same workspace, resulting in unauthorized deletion and configuration loss.

# reproduction steps:

1. Log in as a user who can create API keys.

2. Create a normal CHATFLOW and record its id.

3. Create an API key with only agentflows:delete.

4. Use that API key to send:

```bash

curl -i -X DELETE \

-H 'Authorization: Bearer <agentflows_delete_only_key>' \

http://localhost:8080/api/v1/chatflows/<chatflow_id>

```

5. Observe a 200 OK response, for example:

```json

{"raw":[],"affected":1}

```

6. Read the same id again and observe 404 Not Found.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. Rated impact: confidentiality none, integrity none, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Attack requirements: None — no deployment-specific condition has to hold.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Confidentiality impact: None.
  • Integrity impact: None.
  • Availability impact: High — total loss, or loss the attacker controls.
