Description

The Comment module allows users to reply to comments. In certain cases, an attacker could make comment reply requests that would trigger a denial of service (DOS).

Sites that do not use the Comment module are not affected.

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update drupal/core to 10.1.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6ccv-8fgf-cjpw is resolved across your whole dependency graph.

  3. Workarounds

    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.
