At a glance
This record tracks a medium-severity Missing Authorization vulnerability in the GS Pinterest Portfolio WordPress plugin, affecting versions < 1.8.1. It carries a CVSS score of 4.3 (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 1.8.1; sites on affected versions should update now. Disclosed November 2023.
Vulnerability Overview
The WordPress Pinterest Plugin – Make a Popup, User Profile, Masonry and Gallery Layout plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and a misconfigured nonce check on the _update_shortcode function in all versions up to and including 1.8.0. This makes it possible for authenticated attackers, with subscriber access and above, to update the plugin's shortcodes.
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-862: Missing Authorization
Reaching this weakness in GS Pinterest Portfolio < 1.8.1 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For GS Pinterest Portfolio the fix is 1.8.1: builds < 1.8.1 are affected, anything from 1.8.1 onward is not.
Remediation
Update to version 1.8.1, 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: GS Pinterest Portfolio 1.8.1 closes this, and updating the plugin is the step that ends it.
