6.1.x < 6.1.11. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists that allows an authenticated,
    remote attacker to access potentially sensitive
    information in the system logs.

  - A security bypass vulnerability exists in the XML API
    that allows an authenticated, remote attacker with
    superuser read-only permissions to bypass intended
    restrictions and perform a commit.");
