Vulnerability details
The vulnerability allows a remote user to disclose sensitive information and delete files across workspaces within the same organization.
The vulnerability exists due to missing authorization in the /api/v1/files endpoint when handling GET and DELETE requests with an authenticated API key. A remote user can send crafted requests to list files from other workspaces and delete files by supplying a user-controlled path to disclose sensitive information and delete files across workspaces within the same organization.
The route is protected only by the feat:files feature gate and does not enforce workspace-specific permission checks, which breaks workspace isolation within the organization.
