Prior to version 0.10.0, BorutaIdentityWeb.UserSettingsController.update\/2 atomizes every key of the user-supplied request body via String.to_atom\/1 before any validation. Because String.to_atom interns atoms permanently in the BEAM atom table (default cap 1,048,576 atoms; ERL_MAX_ATOMS), any authenticated end user can send PUT \/users\/settings with a user[]=&#8230; body containing fresh keys per request and exhaust the global VM atom table. Once the table is full, the BEAM aborts with no more index entries in atom_tab and the entire OIDC server (auth, admin, gateway apps in the umbrella) crashes. The route is protected only by require_authenticated_user and a per-IP rate limit of 10 requests\/second; a logged-in end user can hit it. The keys are atomized unconditionally before the downstream Accounts.update_user\/6 call, so even failing updates contribute to exhaustion.
