At a glance
This record tracks a medium-severity Improper Authorization vulnerability in the User Rights Access Manager WordPress plugin, affecting versions <= 1.0.3. It carries a CVSS score of 6.6 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.0.4; sites on affected versions should update now. Disclosed April 2021.
Vulnerability Overview
The User Rights Access Manager plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 1.0.3. This is due to improper implementation of access controls. This makes it possible for authenticated attackers, with administrator-level permissions and above, to take actions or access information for which privileges were removed via the plugin.
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.
CWE-285: Improper Authorization
Reaching this weakness in User Rights Access Manager <= 1.0.3 takes a caller who can reach the endpoint. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.
A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For User Rights Access Manager the fix is 1.0.4: builds <= 1.0.3 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?
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 1.0.4 closes this, and updating the plugin is the step that ends it.
