Description Vladimir Vasilev 2026-10-02 16:21:00 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

An unauthenticated user is able to cause disproportionate CPU load on the Frontend webserver by sending specifically crafted requests to the Frontend popup.testtriggerexpr action, leading to potential denial of service.
