Summary

@rvf/set-get before 7.0.4 contains a prototype pollution flaw in setPath, classified as CWE-1321. An unauthenticated remote attacker can overwrite properties of shared built-in functions by submitting a form field named hasOwnProperty.call through @rvf/core form parsing. This replaces a shared function property and causes a process-wide denial of service that lasts until the process restarts.
