Summary
File Browser is Vulnerable to Insecure Direct Object Reference (IDOR) in Share Deletion Function
Details

Summary

It has been found an Insecure Direct Object Reference (IDOR) vulnerability in the FileBrowser application's share deletion functionality. This vulnerability allows any authenticated user with share permissions to delete other users' shared links without authorization checks.

The impact is significant as malicious actors can disrupt business operations by systematically removing shared files and links. This leads to denial of service for legitimate users, potential data loss in collaborative environments, and breach of data confidentiality agreements. In organizational settings, this could affect critical file sharing for projects, presentations, or document collaboration.

Details

Technical Analysis

The vulnerability exists in/http/share.go at lines 72-82. The shareDeleteHandler function processes deletion requests using only the share hash without comparing the link.UserID with the current authenticated user's ID (d.user.ID). This missing authorization check enables the vulnerability.

var shareDeleteHandler = withPermShare(func(_ http.ResponseWriter, r *http.Request, d *data) (int, error) {
    hash := strings.TrimSuffix(r.URL.Path, "/")
    hash = strings.TrimPrefix(hash, "/")

    if hash == "" {
        return http.StatusBadRequest, nil
    }

    err := d.store.Share.Delete(hash)  // Missing ownership validation
    return errToStatus(err), err
})

PoC

Reproduce Steps:

Prerequisites: Two authenticated user accounts (User A and User B) with share permissions

Step 1: User A creates a share link and obtains the share hash (e.g., MEEuZK-v)

Step 2: User B authenticates and obtains a valid JWT token

Step 3: User B sends DELETE request to /api/share/MEEuZK-v with their own JWT token

Step 4: Observe that User A's share is deleted without authorization

DELETE /api/share/MEEuZK-v HTTP/1.1 Host: filebrowser.local Content-Type: application/json

Impact

The impact is significant as malicious actors can disrupt business operations by systematically removing shared files and links. This leads to denial of service for legitimate users, potential data loss in collaborative environments, and breach of data confidentiality agreements. In organizational settings, this could affect critical file sharing for projects, presentations, or document collaboration.

HireFlow v1.2 is vulnerable to Incorrect Access Control. The application does not enforce object-level authorization on the /candidate/ and /interview/ endpoints. The route handlers retrieve records by the user-supplied ID without verifying that the requesting user is the owner or has an authorized role. Any authenticated user can access any other user's candidate profiles and interview notes by iterating the integer ID in the URL path, constituting a horizontal privilege escalation and full data breach of all records in the system.

Summary
FlowiseAI has Mass Assignment in Variable Update Endpoint that Allows Cross-Workspace Resource Reassignment
Details

Summary

A Mass Assignment vulnerability exists in the variable update endpoint of FlowiseAI.

The endpoint allows authenticated users to modify server-controlled properties such as workspaceId, createdDate, and updatedDate when updating a variable resource.

Due to missing server-side validation and authorization checks, an attacker can manipulate the workspaceId field and reassign variables to arbitrary workspaces.

This behavior may break tenant isolation in multi-workspace environments.

Details

The endpoint responsible for updating variables:

PUT /api/v1/variables/{variableId}

accepts a JSON request body containing the variable definition.

However, the backend does not restrict which attributes can be modified by the client. As a result, user-controlled request bodies can include internal properties that should normally be controlled exclusively by the server.

Server-controlled fields that can be manipulated include:

  • workspaceId
  • createdDate
  • updatedDate

These fields appear to be directly mapped to the database entity without strict input validation or authorization checks.

For example, the following request body was accepted by the server:

{
  "name": "aaa",
  "value": "bbbe",
  "type": "static",
  "createdDate": "2016-03-06T17:59:30.000Z",
  "updatedDate": "2016-03-06T18:00:17.000Z",
  "workspaceId": "11111111-2222-3333-4444-555555555555"
}

The server accepted the attacker-controlled workspaceId and metadata fields and persisted them.

PoC

Request

PUT /api/v1/variables/<VARIABLE_ID>
Content-Type: application/json

{
  "name": "aaa",
  "value": "bbbe",
  "type": "static",
  "createdDate": "2016-03-06T17:59:30.000Z",
  "updatedDate": "2016-03-06T18:00:17.000Z",
  "workspaceId": "11111111-2222-3333-4444-555555555555"
}

Response

{
  "id": "0a2b9f61-4a97-4ff8-b80d-00275ed18674",
  "name": "aaa",
  "value": "bbbe",
  "type": "static",
  "createdDate": "2016-03-06T17:59:30.000Z",
  "updatedDate": "2026-03-06T18:05:17.000Z",
  "workspaceId": "11111111-2222-3333-4444-555555555555"
}

This confirms that the backend accepts and persists attacker-controlled internal properties.

Impact

This vulnerability allows authenticated users to manipulate internal attributes of variable resources.

Possible impacts include:

  1. Cross-workspace reassignment of variables (workspaceId)
  2. Unauthorized modification of metadata (createdDate, updatedDate)
  3. Potential tenant isolation bypass in multi-workspace deployments

In multi-tenant environments, this may allow an attacker to move variables between workspaces without authorization.

7.6 (High)

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
