Information disclosure in Cenodude Crosswatch

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.
