Ally Web Accessibility & Usability - SQLi (CVE-2026-2413)
Description
The Ally Web Accessibility & Usability plugin for WordPress is vulnerable to SQL Injection via the URL path in all versions up to, and including, 4.0.3. This is due to insufficient escaping on the user-supplied URL parameter in the get_global_remediations() method, where it is directly concatenated into an SQL JOIN clause without proper sanitization for SQL context. While esc_url_raw() is applied for URL safety, it does not prevent SQL metacharacters (single quotes, parentheses) from being injected. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via time-based blind SQL injection techniques. The Remediation module must be active, which requires the plugin to be connected to an Elementor account.
psychologyCrowdSec Analysis
CVE-2026-2413 is a SQL injection vulnerability in the Ally – Web Accessibility & Usability WordPress plugin, affecting versions up to 4.0.3. Due to improper sanitization of user-supplied URL parameters in the get_global_remediations() method, unauthenticated attackers can inject malicious SQL code and extract sensitive database information using time-based blind SQL injection techniques. This vulnerability is exploitable when the Remediation module is active and the plugin is connected to an Elementor account, posing a significant risk to affected WordPress sites.
CrowdSec has been tracking this vulnerability and its exploits since 15th of April 2026.
Insights from the CrowdSec network reveal that the attackers trying to exploit CVE-2026-2413 are composed of a fairly even mix of opportunistic and targeted actors. Some attackers employ preliminary reconnaissance, while others use indiscriminate scanning. Additionally, according to week-over-week analysis by CrowdSec, exploitation of CVE-2026-2413 is surging. Attack volumes are spiking well above historical norms, indicating widespread and escalating interest from threat actors. CVE-2026-2413 is currently experiencing high visibility and active exploitation across the internet.
Attackers exploit this vulnerability by sending crafted requests to arbitrary URL paths containing SQL injection payloads (such as /x'OR(EXP(~(SELECT*FROM(SELECT(SLEEP(8)))a)))OR'/), targeting WordPress sites with the Ally – Web Accessibility & Usability plugin enabled. The attack leverages unsanitized URL path input to manipulate SQL queries and extract sensitive data via time-based blind SQL injection.
