Description
@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.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-112309 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
