This breaks tenant isolation in multi-workspace environments.\n\n### Details\nThe endpoint responsible for updating tools:\n\n**PUT /api/v1/tools/{toolId}**\n\naccepts a JSON request body containing tool metadata.\n\nHowever, the server does not restrict which properties may be modified by the client. As a result, user-controlled request bodies can include additional fields that should normally be controlled only by the backend.\n\nServer-controlled fields that can be manipulated include:\n\n1. workspaceId\n2. createdDate\n3. updatedDate\n\nThe request body is directly merged into the underlying database entity without proper DTO validation or authorization checks.\n\n### PoC\nAuthenticate to the Flowise interface.\n\nCapture the request used to update a tool:\n\n```http\nPUT /api/v1/tools/\nCo","public_affected_ranges":["<= 3.1.1"]}],"null_published_at":"2026-11-07T07:07:39.832Z","source_updated_at":"2026-06-09T13:09:58.000Z","source_disclosed_at":"2026-05-14T14:52:40.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-06T15:13:31.161Z"}],"next_cursor":null,"snapshot_revision":"42594"}
