@rvf/set-get before 7.0.4 contains a prototype pollution vulnerability in setPath that allows unauthenticated attackers to overwrite properties of shared built-in functions via inherited Object.prototype methods. Attackers can submit a form field named hasOwnProperty.call through @rvf/core form parsing to replace the shared function property, causing process-wide denial of service until restart.
