CVE-2025-7044 · Severity: high · CVSS 7.7 · Published 2025-12-03
An Improper Input Validation vulnerability exists in the user websocket handler of MAAS. An authenticated, unprivileged attacker can intercept a user.update websocket request and inject the is_superuser property set to true. The server improperly validates this input, allowing the attacker to self-promote to an administrator role. This results in full administrative control over the MAAS deployment.
