CVE-2025-5519Network attack vector

Unauthenticated message disclosure via attacker-chosen identifier

Published Sep 16, 2025 · Updated Sep 16, 2025

Information disclosure in ArgusTech BILGER before 2.4.6 allows remote attackers to read another client's messages by choosing an identifier. The public record states that a requester can select a message identifier, but it does not name the endpoint or disclose how BILGER fails to bind that identifier to the intended client. No authentication or user interaction is required, and the documented consequence is exposure of sensitive data sent for another client.
