Description

RequestHandlerComponent had a vulnerability that would allow well crafted requests to create a denial of service attack. RequestHandlerComponent leverages Xml::build() which allows reading local files. We recommend that all applications using RequestHandlerComponent upgrade, or disable parsing XML payloads.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cakephp/cakephp. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update cakephp/cakephp to 3.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q79m-c546-2g63 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-q79m-c546-2g63 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-q79m-c546-2g63. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
