      "value": "Claude HUD through 0.0.12, patched in commit 234d9aa, contains a path traversal vulnerability that allows attackers to read arbitrary files by supplying an unvalidated transcript_path value via stdin JSON. Attackers can access any file readable by the process and the file metadata is written to a persistent cache file with insufficient permissions, creating a forensic record of accessed paths that survives process exit."

      "value": "Claude HUD hasta la versión 0.0.12, parcheado en el commit 234d9aa, contiene una vulnerabilidad de salto de ruta que permite a los atacantes leer archivos arbitrarios al proporcionar un valor ’transcript_path’ no validado a través de JSON de stdin. Los atacantes pueden acceder a cualquier archivo legible por el proceso y los metadatos del archivo se escriben en un archivo de caché persistente con permisos insuficientes, creando un registro forense de las rutas accedidas que sobrevive al cierre del proceso."
