CVE-2026-55207: Pimcore: Account Takeover via Password Reset URL Injection allows unauthenticated attacker to hijack any admin account with 2FA bypass

August 28, 2026

An unauthenticated attacker takes over any Pimcore admin account by sending a password reset request with an attacker-controlled resetPasswordUrl. The server generates a real cryptographic recovery token, appends it to the attacker’s URL, and emails the link to the victim. When the victim clicks the link in their email, the token is sent to the attacker’s server. The attacker then uses POST /pimcore-studio/api/login/token to authenticate as the victim with full admin privileges. Token login explicitly disables two-factor authentication, so even accounts with TOTP/Google Authenticator are compromised.
