Vulnerable Handlebars (v4.7.7) detected in Power Pages portal scripts

(0) ShareShare
ReportReport
Posted on by SG-20050729-0

Description

We are seeing a vulnerability flagged during security scanning in a Power Pages portal.

  • Issue: Handlebars v4.7.7 (known security issues)
  • Source:
    • https://content.powerapps.com/resource/powerappsportal/dist/postpreform.BootstrapV5.bundle-<hash>.js
  • This script is Microsoft-managed and not part of our custom code.

Concern

Since the dependency is coming from the portal runtime:

  • We cannot upgrade or override it
  • This is impacting our security compliance

Ask

  • Is this a known dependency in Power Pages?
  • Is it already mitigated or a false positive?
  • Any timeline or workaround to address this?
