CVE-2026-53497: Cenodude Crosswatch

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Cenodude Crosswatch: before 0.9.21 (fixed in 0.9.21)
