    "summary": "GLPI is a free asset and IT management software package. From 0.70 until 10.0.26 and 11.0.8, a technician can manipulate the authtype value through the API to change another user's authentication method. Under configurations using the legacy API REST interface or SSO logins, this can change a super-administrator's authentication method and enable account takeover. This issue is fixed in versions 11.0.8 and 10.0.26.",
