CVE-2026-45037

Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.232, Tabby's terminal linkifier passes any detected URI directly to the operating system's protocol handler without validating the protocol scheme. This allows a malicious SSH or Telnet server to send crafted terminal output containing dangerous protocol URIs which Tabby renders as clickable links, triggering arbitrary OS protocol handlers on the victim's machine. This vulnerability is fixed in 1.0.232.

Summary		(es) Tabby (anteriormente Terminus) es un emulador de terminal altamente configurable. Antes de la versión 1.0.232, el enlazador de terminal de Tabby pasa cualquier URI detectado directamente al gestor de protocolo del sistema operativo sin validar el esquema del protocolo. Esto permite a un servidor SSH o Telnet malicioso enviar una salida de terminal manipulada que contiene URIs de protocolo peligrosos que Tabby renderiza como enlaces clicables, activando gestores de protocolo de SO arbitrarios en la máquina de la víctima. Esta vulnerabilidad está corregida en la versión 1.0.232.
