CVE-2026-72760Network attack vector

Email address disclosure via following-list response

Published Aug 10, 2026 · Updated Aug 10, 2026

Information disclosure in MISP CTI-Transmute 1.4.0 and earlier allows remote authenticated users to collect other users' email addresses. The get_following() handler inserts user.email into each account following-list response although the feature needs only the name, user ID, and follow date. Any account can follow users and repeat the request to harvest their email addresses; no integrity or availability impact is reported.
