Description

During startup, an attacker that can man-in-the-middle traffic to and from NTS key exchange servers can trigger a very expensive key validation process due to a vulnerability in webpki.

Impact

This vulnerability can lead to excessive cpu usage on startup on clients configured to use NTS

Patches

Affected users are recommended to upgrade to version 0.3.7

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ntpd, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update ntpd to 0.3.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-37xq-q42p-rv3p is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
