This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 74% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Affected versions of cti-transmute fail to HTML-escape attacker-controlled values used in ECharts Sunburst and Treemap tooltip formatters. Slice names may originate directly from STIX or MISP data, including STIX types, relationship_type, pattern prefixes, and MISP category/type values. Since ECharts interprets the formatter return value as HTML, crafted values can inject markup or script-capable content into the tooltip.

An attacker who can cause malicious conversion data to be processed can therefore inject content that executes when another user views the visualization and hovers over the affected slice. The patch replaces direct interpolation with dedicated formatter functions that call escapeHtml() on p.name, p.data.value, and p.value.
