At a glance

This record tracks a critical-severity Cross-Site Request Forgery (CSRF) vulnerability in the Feed Them Social WordPress plugin, affecting versions <= 2.9.8.5. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.9.8.6; sites on affected versions should update now. Disclosed July 2022.

Vulnerability Overview

The Feed Them Social plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.9.8.5. This is due to missing or incorrect nonce validation on the fts_refresh_token_ajax function. This makes it possible for unauthenticated attackers to update plugin settings.

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, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

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

Reaching this weakness in Feed Them Social <= 2.9.8.5 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 Feed Them Social the fix is 2.9.8.6: builds <= 2.9.8.5 are affected, anything from 2.9.8.6 onward is not.

Remediation

Update to version 2.9.8.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Feed Them Social: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Feed Them Social 2.9.8.6 closes this, and updating the plugin is the step that ends it.
