CVE-2026-55207 Details
Description
Pimcore is an Open Source Data & Experience Management Platform. Prior to 2025.4.6 and 2026.1.6, 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. This issue is fixed in versions 2025.4.6 and 2026.1.6.
A vulnerability allowing account takeover has been identified in Pimcore versions prior to 2025.4.6 and 2026.1.6. An unauthenticated attacker who knows a valid admin username can hijack any admin account by sending a password reset request with a manipulated resetPasswordUrl. The server generates a legitimate cryptographic recovery token, appends it to the attacker's URL, and emails the link to the victim. When the victim clicks the link, the token is sent to the attacker, who can use it to authenticate as the victim with full admin privileges, bypassing two-factor authentication.
Users can update to Pimcore versions 2025.4.6 or 2026.1.6, where this vulnerability has been fixed.
