At a glance
This record tracks a high-severity Improper Access Control vulnerability in the User Rights Access Manager WordPress plugin, affecting versions <= 1.0.7.

The issue is fixed in version 1.0.8; sites on affected versions should update now. Disclosed August 2021.
Vulnerability Overview
The User Rights Access Manager plugin for WordPress is vulnerable to Access Restriction Bypass via the 'page' parameter in versions up to, and including, 1.0.7. This makes it possible for admin+ attackers to gain full site access even when certain web pages have been disabled.
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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-284: Improper Access Control
User Rights Access Manager <= 1.0.7 carries this weakness at page, and reaching it takes a caller who can reach the endpoint. 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 User Rights Access Manager the fix is 1.0.8: builds <= 1.0.7 are affected, anything from 1.0.8 onward is not.
Remediation
Update to version 1.0.8, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: User Rights Access Manager 1.0.8 closes this, and updating the plugin is the step that ends it.
