CVE-2026-72751 is a stored cross-site scripting vulnerability in CTI-Transmute’s conversion graph and associated raw JSON viewer affecting versions 1.4 and earlier. Attacker-controlled values derived from converted MISP or STIX content were propagated to multiple HTML-parsing sinks in the graph interface without sufficient output neutralization. Affected data paths included node labels, node sublabels, edge labels, node properties, edge properties, hash algorithm names, child attributes, and STIX object types. The Pivotick graph library rendered some of these values through HTML-resolving code paths, causing crafted markup to be interpreted as HTML rather than displayed as text. Additional exposure existed in the raw JSON viewer, where a graph node’s raw object was inserted into a new document using document.write() with interpolated HTML, allowing crafted JSON content to break out of the intended preformatted block and inject executable markup. A later patch also addressed graph properties panel vectors reachable when a node is hovered over or selected.
