CVE-2026-73157

Affected versions of cti-transmute render data obtained from a remote MISP instance into the event-browser interface using HTML interpolation. Because fields such as event IDs, event information, organization names, tags, tag colors, TLP labels, distribution labels, and error/flash text may be controlled by the remote MISP server, a malicious or compromised remote instance could return crafted values that inject HTML or script-capable content into the cti-transmute interface. The patch explicitly notes that remote-derived values must not reach innerHTML, and replaces string-built rows and badges with DOM nodes populated through textContent. It also restricts remote-controlled tag colors to six-digit hexadecimal values, preventing malicious CSS values such as url(...).

Summary		(es) Versiones afectadas de cti-transmute renderizan datos obtenidos de una instancia MISP remota en la interfaz del navegador de eventos utilizando interpolación HTML. Debido a que campos como IDs de eventos, información de eventos, nombres de organizaciones, etiquetas, colores de etiquetas, etiquetas TLP, etiquetas de distribución y texto de error/flash pueden ser controlados por el servidor MISP remoto, una instancia remota maliciosa o comprometida podría devolver valores manipulados que inyecten contenido HTML o capaz de ejecutar scripts en la interfaz de cti-transmute. El parche señala explícitamente que los valores derivados remotamente no deben llegar a innerHTML, y reemplaza las filas y distintivos construidos con cadenas por nodos DOM poblados a través de textContent. También restringe los colores de etiquetas controlados remotamente a valores hexadecimales de seis dígitos, impidiendo valores CSS maliciosos como url(...).
