At a glance

CVE-2024-6751 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Social Auto Poster WordPress plugin, affecting versions <= 5.3.14. It carries a CVSS score of 6.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. 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 Cross-Site Request Forgery in versions up to, and including, 5.3.14. This is due to missing or incorrect nonce validation on multiple functions. This makes it possible for unauthenticated attackers to add, modify, or delete post meta and plugin options.

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 privileges on the target site.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Social Auto Poster <= 5.3.14 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. 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?

The attempt arrives as an ordinary request to Social Auto Poster: WordSec's web application firewall inspects request payloads before WordPress loads them. 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.
