CVE-2026-55207 pimcore CVE debrief
CVE-2026-55207 is a high-severity vulnerability in Pimcore, an Open Source Data & Experience Management Platform. An unauthenticated attacker who knows a valid admin username can take 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 supplied URL, and emails the link to the victim; when the victim clicks the link, the token is sent to the attacker and can be used with POST /pimcore-studio/api/login/token to authenticate with full admin privileges while bypassing two-factor authentication.
