Vulnerability Overview
The Rate my Post - WP Rating System plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.4.1 due to missing validation on a user controlled key. This can allow users with publishing access to manipulate feedback and ratings.
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-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in Rate My Post < 3.4.2 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Rate My Post the fix is 3.4.2: builds < 3.4.2 are affected, anything from 3.4.2 onward is not.
Remediation
Update to version 3.4.2, 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: Rate My Post 3.4.2 closes this, and updating the plugin is the step that ends it.
