CVE-2025-15521Network attack vectorHinoki check available

Account takeover via nonce-only password reset

Published Jan 21, 2026 · Updated Jan 21, 2026

Authorization bypass in Kodezen LLC Academy LMS 3.5.0 and earlier allows remote attackers to take over WordPress accounts. The password-reset path accepts an attacker-selected account and authorizes the password change with only a publicly exposed nonce, without verifying identity. No authentication is required; changing an administrator's password grants administrative access to the WordPress site.
