Who should care

cPanel/WHM administrators, hosting teams, and platform owners who use EasyApache 4 to manage Node.js packages—especially environments relying on Node.js 20.x or 22.x and any deployment that uses the Node.js permission model.

Technical summary

According to the vendor release note, EasyApache 4 25.43 ships updated Node.js 20.20.0 and Node.js 22.22.0 packages that address CVE-2025-55132. The vulnerability is identified as an HTTP Request Smuggling issue in the permission model. The supplied corpus does not include a CVSS score, exploit details, or CVE publication/modification timestamps.

Defensive priority

High for systems running EasyApache 4-managed Node.js packages. Prioritize the update on internet-facing or multi-tenant hosting environments, and treat any use of the Node.js permission model as an additional reason to move quickly.

Recommended defensive actions

  • Check whether your cPanel/WHM systems use EasyApache 4 Node.js packages affected by the 25.43 update.
  • Upgrade to EasyApache 4 25.43 or a later vendor release that includes the Node.js fixes.
  • Confirm that the installed Node.js packages reflect the vendor-updated 20.20.0 and 22.22.0 builds.
  • Re-test Node.js applications and any middleware that depends on request parsing or routing after the update.
  • Continue monitoring cPanel release notes for related fixes released alongside the same maintenance cycle.
