CVE-2026-8181 Mass Scanner / Exploit
Burst Statistics 3.4.0 - 3.4.1.1 — Authentication Bypass to Admin Account Takeover
Educational / Authorized Testing Only
BREAKTHROUGH:
1. is_mainwp_authenticated() calls wp_authenticate_application_password() but
only checks is_wp_error(). When called outside REST API context, WP returns null.
2. null is NOT WP_Error → auth check PASSES → wp_set_current_user(admin_id).
3. X-BurstMainWP: 1 header triggers this path during plugins_loaded.
4. Attacker hits /burst/v1/mainwp-auth with Basic Auth (any password) +
X-BurstMainWP: 1 → gets WordPress Application Password token.
5. Token = base64(username:app_password) → persistent admin access.
