6.2.8-h13, or 6.3.x prior to 6.3.3-h14. It is, therefore, affected by multiple vulnerabilities collectively known as
Global Un-Protect:

  - Local privilege escalation vulnerabilities enable a local user to escalate their privileges to root on macOS
    and Linux. (CVE-2026-0299)

  - A buffer overflow vulnerability enables a man-in-the-middle (MitM) attacker or a rogue gateway to disrupt
    system processes and potentially execute arbitrary code with root privileges. (CVE-2026-0297)

  - A race condition enables a locally authenticated low-privileged attacker to escalate their privileges to
    root. (CVE-2026-0295)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
