Technical description
CTI-Transmute is affected by a stored cross-site scripting (XSS) vulnerability in the conversion graph used to visualise converted MISP and STIX content.
Attacker-controlled values originating from converted CTI data were passed to multiple HTML-parsing sinks in the graph user interface without sufficient neutralisation. In particular, node labels, node sublabels, edge labels, node properties, edge properties, and node types could contain crafted HTML or JavaScript content.
The Pivotick graph library renders some of these values through HTML-parsing operations. Consequently, a malicious value such as an HTML element containing an event handler could be interpreted as markup rather than displayed as plain text. The first remediation explicitly notes that Pivotick rendered node and edge labels as HTML and therefore introduced escaping before data was handed to the graph renderer.
A separate vulnerable sink was present in the Open raw JSON functionality. The raw object associated with
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-72751?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-72751 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
