CVE-2025-30825 is a high-severity Incorrect Privilege Assignment vulnerability in the WPC Smart Linked Products WordPress plugin, affecting versions <= 1.3.5.

Vulnerability Overview

The WPC Smart Linked Products – Upsells & Cross-sells for WooCommerce plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.3.5. This is due to the plugin not properly restricting roles. This makes it possible for authenticated attackers, with contributor-level access and above, to elevate their privileges.

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-266: Incorrect Privilege Assignment

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.

Remediation

Update to version 1.3.6, 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: WPC Smart Linked Products 1.3.6 closes this, and updating the plugin is the step that ends it.
