Description

A vulnerability was found in vuejs vue-cli up to 5.0.8. It has been rated as problematic. This issue affects the function HtmlPwaPlugin of the file packages/@vue/cli-plugin-pwa/lib/HtmlPwaPlugin.js of the component Markdown Code Handler. The manipulation leads to inefficient regular expression complexity. The attack may be initiated remotely.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Remediation status

    The records we use list no patched version of @vue/cli-plugin-pwa for GHSA-79vf-hf9f-j9q8. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. 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.
