Summary
Map-OS 5.0.0 to before 5.2.2 contains a privilege escalation vulnerability in the REST users API that allows non-administrator operators holding the cUsuario permission to bypass permission-delegation and super-administrator protections. Attackers can send POST, PUT, or DELETE requests to /api/v1/usuarios to assign the Administrador group, reset the super administrator password, or delete higher-privileged users.

Questions about CVE-2026-125382
Is CVE-2026-125382 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
A non-administrator operator who holds the cUsuario permission can use the Map-OS users API to assign the Administrador group to an account, reset the super administrator password, or delete users with higher privileges than their own.Source: vulncheck.com, github.com
Which versions are affected by CVE-2026-125382?
mapos: from 5.0.0-beta.1 before 5.2.2.Source: cve.now feed data
Am I affected, and how do I check?
Map-OS versions from 5.0.0-beta.1 up to but not including 5.2.2 are affected, and only where the REST API is enabled (API_ENABLED=true) and an operator account holds the cUsuario permission. To check, look at the installed version and at whether API_ENABLED is set to true in the configuration.Source: vulncheck.com, github.com
How do I fix CVE-2026-125382?
Upgrade Map-OS to version 5.2.2 or later, which contains the fix listed in the mapos v5.2.2 Release Notes.Source: vulncheck.com, github.com
