Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for onPhase/onPhase Forms.
  2. 2Review the reported fix. Source-reported solution: * Upgrade to 11.0.17 * The unauthenticated registration endpoint has been removed. * Rules run in a sandbox that blocks access to unapproved Java classes. * The Document Service endpoint (/service) is disabled by default (frevvo.documentServiceApi.enabled=false). Re-enabling it brings back the risk of server-side request forgery and is done at the customer's own risk. * Customers who cannot upgrade immediately should block /frevvo/web/webapp/register and /frevvo/web/**/service at their reverse proxy or web application firewall.
