CVE-2026-72759Network attack vector

Data disclosure via deleted-conversion authorization bypass

Published Aug 10, 2026 · Updated Aug 10, 2026

Missing authorization in MISP Project CTI-Transmute 1.4.0 and earlier allows remote attackers to read retained conversion data. The conversion-history details endpoint treats a missing conversion object as grounds to skip access.can_see, so a deleted conversion's history input and output remain readable. Exploitation requires a corresponding history identifier; disclosure is limited to retained conversion content.
