icinga2 was updated to 2.12.5:

 Version 2.12.5 fixes two security vulnerabilities that may lead to

privilege escalation for authenticated API users. Other improvements
include several bugfixes related to downtimes, downtime notifications, and
more reliable connection handling.

 * Security

   - Don't expose the PKI ticket salt via the API. This may lead to
     privilege escalation for authenticated API users by them being able
     to request certificates for other identities (CVE-2021-32739)

   - Don't expose IdoMysqlConnection, IdoPgsqlConnection, and
     ElasticsearchWriter passwords via the API (CVE-2021-32743)

   Depending on your setup, manual intervention beyond installing the new

versions may be required, so please read the more detailed information in
the release blog post carefully.

 * Bugfixes

   - Don't send downtime end notification if downtime hasn't started #8878
   - Don't let a failed downtime creation block the others #8871
   - Support downtimes and comments for checkables with long names #8870
   - Trigger fixed downtimes immediately if the current time matches
     (instead of waiting for the timer) #8891
   - Add configurable timeout for full connection handshake #8872
 * Enhancements
   - Replace existing downtimes on ScheduledDowntime change #8880
   - Improve crashlog #8869
