  - CVE-2022-24714: When using service custom variables in role restrictions, and regularly
  decommissioning service objects, users with said roles may still have access to a collection of
  content. This affects installations of Icinga Web 2 with the IDO writer enabled. Note that this
  only applies if a role has implicitly permitted access to hosts, due to permitted access to at
  least one of their services. If access to a host is permitted by other means, no sensible
  information has been disclosed to unauthorized users.");
