At a glance
CVE-2024-35700 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the UserPro - Community and User Profile WordPress Plugin WordPress plugin, affecting versions 5.1.8. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication.

Vulnerability Overview
The UserPro - Community and User Profile WordPress Plugin plugin for WordPress is vulnerable to unauthenticated account takeover in all versions up to, and including 5.1.8. This makes it possible for unauthenticated attackers to take over user accounts and gain highly privileged access to sites.
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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-288: Authentication Bypass Using an Alternate Path or Channel
Reaching this weakness in UserPro - Community and User Profile WordPress Plugin 5.1.8 takes no account at all. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.
The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. For UserPro - Community and User Profile WordPress Plugin the fix is 5.1.9: builds 5.1.8 are affected, anything from 5.1.9 onward is not.
Remediation
Update to version 5.1.9, 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: UserPro - Community and User Profile WordPress Plugin 5.1.9 closes this, and updating the plugin is the step that ends it.
