CVE-2026-2752Network attack vector

Information disclosure via verbose API error responses

Published Mar 6, 2026 · Updated Mar 6, 2026

Information disclosure in NAVTOR NavBox 4.12.0.3 allows remote attackers to obtain internal details via crafted API requests. The /api/ais-data handler leaves crafted-request exceptions unhandled, and the .NET server returns verbose stack traces in HTTP responses. No authentication is required; exposed class names, method calls, and library references reveal application structure without changing data or service state.
