Ally WordPress Plugin Vulnerability CVE-2026-2413: Unauthenticated SQL Injection Explained

An unauthenticated SQL Injection vulnerability has been identified in the Ally – Web Accessibility & Usability plugin used in Elementor-based WordPress environments. With over 400,000 active installations globally, this issue has a potentially wide impact surface.

However, this is not a vulnerability that can be exploited across all WordPress environments by default. Exploitation depends on specific conditions. This article outlines the affected plugin, root cause, and what security teams should verify.



CVE-2026-2413 - Affected Plugin

Ally is a WordPress plugin provided by Elementor, currently used by over 400,000 websites according to WordPress.org. The plugin improves website accessibility by supporting features such as text readability, keyboard navigation, and screen reader compatibility. It also provides guidance on identifying and fixing accessibility issues. This issue is tracked as CVE-2026-2413, affecting Ally versions 4.0.3 and below, and represents a SQL Injection vulnerability in a WordPress plugin.


Root Cause of the Vulnerability

The issue originates from the get_global_remediations() method. This method processes a user-supplied URL by directly concatenating it into a SQL JOIN clause. Although esc_url_raw() is applied, this function only validates URL format and does not protect against SQL Injection.

As a result, an attacker can attempt time-based SQL Injection attacks to infer database information. Sensitive data such as password hashes could potentially be exposed.


The issue has been fixed by implementing parameter binding using wpdb->prepare().

Affected versions: 4.0.3 and below

Patched version: 4.1.0


Are All Environments Using This Plugin Vulnerable?

Not all environments using this plugin are equally vulnerable. Exploitation is only possible when all of the following conditions are met:


  • A vulnerable version is in use (4.0.3 or below)

  • The Remediation feature is enabled

  • The plugin is connected to an Elementor account


The Remediation feature analyzes accessibility issues and provides guidance on how to fix them. The vulnerability is triggered only when this feature is active and the plugin is linked to an Elementor account.

From a security perspective, it is important to evaluate actual operational conditions, not just installation status.


Why This Is Still Considered High Risk

There are currently no confirmed reports of large-scale exploitation. However, this vulnerability is unauthenticated and can be exploited remotely, making it suitable for automated attacks. Combined with its large install base of over 400,000 sites, the potential attack surface is significant. According to BleepingComputer, only about 36% of sites have upgraded to version 4.1.0. This suggests that more than 250,000 sites may still be running vulnerable versions.

Organizations should verify whether they are exposed to the Ally WordPress plugin vulnerability (CVE-2026-2413) within their environments.


What Security Teams Should Check

It is important not to confuse WordPress core updates with plugin updates. WordPress released versions 6.9.2 and 6.9.3 on March 10, 2026, followed by 6.9.4 on March 11, which is the latest security release. Updating the core alone does not resolve this SQL Injection vulnerability in the plugin.

Security teams should verify the following separately:


  • Ally plugin updated to version 4.1.0 or later

  • WordPress core updated to version 6.9.4


This case highlights an unauthenticated SQL Injection vulnerability in a widely deployed WordPress plugin. However, risk cannot be assessed based on installation alone. For environments using Ally, it is important to verify not only the plugin version but also whether the relevant feature is enabled and whether it is connected to an Elementor account. Updating to version 4.1.0 or later should be prioritized.

More importantly, vulnerabilities like this require more than detection. They require understanding which assets are affected and making the right operational decisions on what to prioritize and how to respond.
