At a glance

CVE-2024-1288 is a medium-severity Improper Access Control vulnerability in the Schema & Structured Data for WP & AMP WordPress plugin, affecting versions <= 1.26. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.27; sites on affected versions should update now. Disclosed February 2024, reported by Ngô Thiên An (ancorn_).

Vulnerability Overview

The Schema & Structured Data for WP & AMP plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'saswp_reviews_form_render' function in all versions up to, and including, 1.26. This makes it possible for authenticated attackers, with contributor access and above, to modify the plugin's stored reCaptcha site and secret keys, potentially breaking the reCaptcha functionality.

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-284: Improper Access Control

Schema & Structured Data for WP & AMP <= 1.26 carries this weakness at saswp_reviews_form_render, and reaching it takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Schema & Structured Data for WP & AMP the fix is 1.27: builds <= 1.26 are affected, anything from 1.27 onward is not.

Remediation

Update to version 1.27, 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: Schema & Structured Data for WP & AMP 1.27 closes this, and updating the plugin is the step that ends it.
