What is CVE-2018-11116?

OpenWrt contains a vulnerability related to improper access control in the rpcd configuration files, specifically in /etc/config/rpcd and /usr/share/rpcd/acl.d. This flaw permits remote authenticated users to invoke arbitrary methods over HTTP that should be restricted to specific users. Such unintended access can potentially expose sensitive information or lead to execution of unauthorized code through namespaces like file, log, and service. Although the developer contests the classification of this as a vulnerability, the implications for user security are significant.
