CVE-2026-53497

CrossWatch (CW) is a synchronization engine. Prior to version 0.9.21, GET /api/app-auth/status is accessible without authentication and returns the other_sessions array, which exposes metadata of all active sessions — including originating IP addresses, User-Agent strings, internal session IDs, and creation/expiry timestamps. Any unauthenticated network attacker can enumerate this data without credentials. Version 0.9.21 fixes the issue.

Summary		(es) CrossWatch (CW) es un motor de sincronización. Antes de la versión 0.9.21, GET /API/app-auth/status es accesible sin autenticación y devuelve el array other_sessions, que expone metadatos de todas las sesiones activas - incluyendo direcciones IP de origen, cadenas de User-Agent, IDs de sesión internas y marcas de tiempo de creación/caducidad. Cualquier atacante de red no autenticado puede enumerar estos datos sin credenciales. La versión 0.9.21 corrige el problema.
