Description

The content module is a module to parse HTTP Content-* headers. It is used by the hapijs framework to provide this functionality. The module is vulnerable to regular expression denial of service when passed a specifically crafted Content-Type or Content-Disposition header.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update content to 3.0.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x6wp-rfwh-hcx7 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.

Frequently Asked Questions

Affected versions of `content` are vulnerable to a regular expression denial of service when parsing malicious `Content-Type` and `Content-Disposition` headers. ## Recommendation Update to version 3.0.6 or later.
