CVE-2026-8181 Details
Description
The Burst Statistics – Privacy-Friendly WordPress Analytics (Google Analytics Alternative) plugin for WordPress is vulnerable to Authentication Bypass in versions 3.4.0 to 3.4.1.1. This is due to incorrect return-value handling in the `is_mainwp_authenticated()` function when validating application passwords from the Authorization header. This makes it possible for unauthenticated attackers, with knowledge of an administrator username, to impersonate that administrator for the duration of the request by supplying any random Basic Authentication password achieving privilege escalation.
A vulnerability allowing authentication bypass has been identified in the Burst Statistics WordPress plugin, specifically in versions 3.4.0 to 3.4.1.1. The issue arises from improper handling of return values in the 'is_mainwp_authenticated()' function, which validates application passwords from the Authorization header. This flaw enables unauthenticated attackers who know an administrator's username to impersonate that administrator for the duration of the request by using any random Basic Authentication password, thereby escalating privileges.
Users are advised to update the Burst Statistics WordPress plugin to version 3.4.2 or later.
