EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 85% 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 allow a tag's icon value to be stored and later interpolated into HTML through Vue's v-html. The helper mapIcon() previously constructed an HTML string directly from the icon value:

Because the icon is user-supplied, a crafted value could break out of the intended markup and inject attacker-controlled HTML. When the affected tag was later rendered, including on the administrative triage interface, the payload could execute in the viewer's browser.

The patch mitigates the issue at multiple layers: v-html is replaced with Vue :class binding, mapIcon() now returns only a constrained FontAwesome class string, and the backend validates icons against the FontAwesome catalogue or a strict [a-z0-9-]{1,40} slug pattern before storing them.
