Dolibarr before 24.0.0 contains an improper authorization vulnerability in the Members REST API that allows attackers with only member-creation rights to reset the password of any user account, including the system administrator, without verifying password-change permissions. Attackers can supply an arbitrary user account identifier and new password in the request body to overwrite credentials and immediately lock out the legitimate account holder.
