CVE-2026-121020
User and Role Enumeration by Low-Privileged Users in Axxon One Security Configuration API
Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) in the security configuration API in AxxonSoft Axxon One before 3.2.0 on Windows and Linux allows a remote authenticated user with limited privileges to enumerate all user accounts and roles configured in the system via the user configuration request, which returned the complete lists of users and roles regardless of the caller's permissions.
Fixes and workarounds
Fix
Upgrade Axxon One to version 3.2.0 or later, where the user configuration request returns only the data the requesting user is permitted to see.
