At a glance

CVE-2024-6754 is a medium-severity Missing Authorization vulnerability in the Social Auto Poster WordPress plugin, affecting versions <= 5.3.14. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 5.3.15; sites on affected versions should update now. Disclosed July 2024, reported by István Márton.

Vulnerability Overview

The Social Auto Poster plugin for WordPress is vulnerable to unauthorized modification of data to a missing capability check on the ‘wpw_auto_poster_update_tweet_template’ function in all versions up to, and including, 5.3.14. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary post metadata.

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

Social Auto Poster <= 5.3.14 carries this weakness at wpw_auto_poster_update_tweet_template, and reaching it takes an account at Subscriber level or above. 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 Social Auto Poster the fix is 5.3.15: builds <= 5.3.14 are affected, anything from 5.3.15 onward is not.

Remediation

Update to version 5.3.15, 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: Social Auto Poster 5.3.15 closes this, and updating the plugin is the step that ends it.
