      "value": "Claude HUD through 0.0.12, patched in commit 234d9aa, constructs OSC 8 terminal hyperlink escape sequences using raw cwd and branchUrl values without stripping control characters or encoding embedded values, allowing attackers to inject arbitrary ANSI codes into terminal sessions. Attackers can embed ESC+backslash sequences in the current working directory or branch URL to execute malicious ANSI codes including text color changes, forged prompts, and OSC 52 clipboard writes, or trigger outbound HTTP requests to attacker-controlled remotes when hyperlinks are clicked."

      "value": "Claude HUD hasta la versión 0.0.12, parcheado en el commit 234d9aa, construye secuencias de escape de hipervínculo de terminal OSC 8 utilizando valores brutos de cwd y branchUrl sin eliminar caracteres de control ni codificar valores incrustados, permitiendo a los atacantes inyectar códigos ANSI arbitrarios en las sesiones de terminal. Los atacantes pueden incrustar secuencias ESC+barra invertida en el directorio de trabajo actual o en la URL de la rama para ejecutar códigos ANSI maliciosos, incluyendo cambios de color de texto, avisos falsificados y escrituras en el portapapeles OSC 52, o activar solicitudes HTTP salientes a remotos controlados por el atacante cuando se hace clic en los hipervínculos."
