CVE-2026-43892Public exploitNetwork attack vector

One-click code execution via terminal format injection

Published May 12, 2026 · Updated May 12, 2026

Code injection in AntSword before 2.1.16 allows remote attackers controlling a managed server to execute commands after a link click. The noxss() path passes terminal syntax into term.echo(), where jquery.terminal turns attacker-controlled output into a JavaScript link inside a Node-integrated Electron webview. Exploitation requires AntSword to connect to the attacker's server and a user to click the rendered link; execution inherits the AntSword process privileges.
