The helper mapIcon() previously constructed an HTML string directly from the icon value:\n\n\n\u003ci class=\"fas fa-${name}\"\u003e\u003c/i\u003e\n\n\nBecause 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\u0027s browser.\n\n\nThe 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."

In particular, node labels, node sublabels, edge labels, node properties, edge properties, and node types could contain crafted HTML or JavaScript content.\u003c/p\u003e\u003cp\u003eThe 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.\u003c/p\u003e\u003cp\u003eA separate vulnerable sink was present in the \u003cstrong\u003eOpen raw JSON\u003c/strong\u003e functionality. The raw object associated with a graph node was inserted into a new document using \u003ccode\u003edocument.write()\u003c/code\u003e and an interpolated HTML string. Crafted JSON content could therefore break out of the intended \u003ccode\u003e\u0026lt;pre\u0026gt;\u003c/code\u003e element and inject executable markup. The fix replaced this construction with DOM APIs and assigns the JSON using \u003ccode\u003etextContent\u003c/code\u003e.\u003c/p\u003e\u003cp\u003eThe initial correction did not cover all Pivotick rendering paths. A subsequent patch addressed additional XSS vectors in the graph properties panel. Values derived from the original CTI object\u2014including property names, property values, hash algorithm names, child attributes, edge properties, and STIX object types\u2014could still reach Pivotick\u0027s HTML resolver.

          "value": "CTI-Transmute is affected by a stored cross-site scripting (XSS) vulnerability in the conversion graph used to visualise converted MISP and STIX content.\n\nAttacker-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.\n\nThe 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.\n\nA separate vulnerable sink was present in the Open raw JSON functionality. The raw object associated with a graph node was inserted into a new document using document.write() and an interpolated HTML string. Crafted JSON content could therefore break out of the intended \u003cpre\u003e element and inject executable markup. The fix replaced this construction with DOM APIs and assigns the JSON using textContent.\n\nThe initial correction did not cover all Pivotick rendering paths. A subsequent patch addressed additional XSS vectors in the graph properties panel. Values derived from the original CTI object\u2014including property names, property values, hash algorithm names, child attributes, edge properties, and STIX object types\u2014could still reach Pivotick\u0027s HTML resolver. According to the patch, Pivotick\u0027s tryResolveHTMLElement processes string values using template.innerHTML, allowing malicious markup to execute when a graph node is hovered over or selected.\n\nThe complete remediation therefore:\n\n  *  HTML-escapes node labels, node sublabels, and edge labels before they are passed to Pivotick.\n  *  Restricts graph node type values to a safe identifier character set.\n  *  Wraps node and edge property values in DOM elements populated through textContent, preventing Pivotick from treating attacker-controlled strings as HTML.\n  *  Replaces the raw-JSON popup\u0027s interpolated document.write() with DOM construction and textContent."
