CVE-2021-20407Network attack vector

Developer email disclosure via bundled Node.js source

Published Feb 12, 2021 · Updated Sep 17, 2024

Information disclosure in IBM Security Verify Information Queue 1.0.6 and 1.0.7 allows remote attackers to obtain a developer email address. A bundled Node.js package embeds the address directly in its source code, making it retrievable without authentication over a network. The disclosure is limited to that contact detail, but it can support reconnaissance and subsequent attacks against the deployment.
