the CONFSERVER-103710 advisory.

  - This DoS (Denial of Service) vulnerability allows an unauthenticated attacker to cause a resource to be 
    unavailable for its intended users by temporarily or indefinitely disrupting services of a host connected
    to a network which has no impact to confidentiality, no impact to integrity, high impact to availability, 
    and requires no user interaction. (CVE-2026-33750)
