At a glance

CVE-2024-1318 is a medium-severity Missing Authorization vulnerability in the RSS Aggregator by Feedzy WordPress plugin, affecting versions <= 4.4.2. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 4.4.3; sites on affected versions should update now. Disclosed February 2024, reported by Lucio Sá.

Vulnerability Overview

The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'feedzy_wizard_step_process' and 'import_status' functions in all versions up to, and including, 4.4.2. This makes it possible for authenticated attackers, with Contributor access and above, who are normally restricted to only being able to create posts rather than pages, to draft and publish posts with arbitrary content.

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 integrity.

CWE-862: Missing Authorization

RSS Aggregator by Feedzy <= 4.4.2 carries this weakness at feedzy_wizard_step_process, and reaching it 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 RSS Aggregator by Feedzy the fix is 4.4.3: builds <= 4.4.2 are affected, anything from 4.4.3 onward is not.

Remediation

Update to version 4.4.3, 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: RSS Aggregator by Feedzy 4.4.3 closes this, and updating the plugin is the step that ends it.
