What is CVE-2026-71504?

Dolibarr ERP & CRM prior to version 24.0.0 is susceptible to an improper authorization flaw within the Members REST API. This vulnerability enables attackers who possess member-creation rights to reset the passwords of any user account, including sensitive accounts like that of the system administrator. By sending a request with a user account identifier and a new password without the requisite password-change permissions, attackers can replace valid user credentials. This allows them to instantly lock out legitimate users, posing a significant security risk.
