At a glance
This record tracks a medium-severity Improper Access Control vulnerability in the Leads5050 Visitor Insights WordPress plugin, affecting versions < 1.0.4. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview
The Leads5050 Visitor Insights plugin for WordPress is vulnerable to Arbitrary License Change in versions before 1.0.4. This is due to insufficient access control on the leads5050_set_license AJAX action. This makes it possible for unauthenticated attackers to set and modify arbitrary licenses in the plugin settings.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-284: Improper Access Control
Reaching this weakness in Leads5050 Visitor Insights < 1.0.4 takes no account at all. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.
Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Leads5050 Visitor Insights the fix is 1.0.4: builds < 1.0.4 are affected, anything from 1.0.4 onward is not.
Remediation
Update to version 1.0.4, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Leads5050 Visitor Insights 1.0.4 closes this, and updating the plugin is the step that ends it.
