burstbv Burst Statistics – Privacy-Friendly WordPress Analytics (Google Analytics Alternative) — Burst Statistics 3.4.0 - 3.4.1.1 - Authentication Bypass to Admin Account Takeover

Description · from the CVE record

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.
