CVE-2026-54162 is an improper neutralization of terminal escape/control sequences vulnerability in Ember versions before 1.4.2. Ember's interactive terminal user interface can render attacker-controlled fields from Caddy access logs without adequately neutralizing terminal control sequences. Crafted HTTP request data recorded by a monitored Caddy instance can therefore be interpreted by the terminal emulator of an operator viewing the interactive TUI.
