Pivotick vulnerabilities

Pivotick contains a DOM-based XSS vulnerability in UI element resolution and icon-rendering utilities. The tryResolveHTMLElement function treats any resolved string as HTML markup, and createIcon inserts SVG icons without sanitization. An unauthenticated attacker can provide a crafted graph, property value, or SVG icon, leading to JavaScript execution in the victim's browser.

Pivotick did not validate the URI scheme of node imagePath values, allowing an attacker to set a malicious URI. When a victim renders the graph, the browser could initiate an unintended request or invoke scheme-specific handling.

Pivotick used plain JavaScript objects as lookup tables indexed by caller-controlled node identifiers. Identifiers matching inherited properties from Object.prototype (e.g., constructor, __proto__) could be misinterpreted, leading to omitted nodes, incorrect hierarchies, bypassed cycle detection, or exceptions causing denial of service.

Pivotick's Markdown node-reference renderer fails to HTML-escape the attacker-controlled nodeName value, allowing injection of malicious HTML attributes or elements. This can lead to arbitrary JavaScript execution in the victim's browser.

Pivotick has an uncontrolled-recursion vulnerability when processing graph and node data. Recursive graph traversals and JSON rendering can exhaust the JavaScript call stack with specially crafted data, causing page or browser crashes.

Pivotick contains a cross-site scripting vulnerability in the inspect and edit node modals. Node labels and descriptions from graph data are interpolated directly into HTML, allowing an attacker to inject malicious JavaScript.

Pivotick fails to sanitize attacker-controlled SVG markup from the style.svgIcon property before inserting it into the document. The vulnerable code assigns SVG markup to innerHTML, allowing execution of event handlers like <image> with onerror. An attacker can execute arbitrary JavaScript in the application context.

Pivotick contains an XSS vulnerability in the sidebar property-list component. Link-like property values (url, uri, href, link, website, homepage) were rendered as hyperlinks without URL scheme validation. An attacker can supply a malicious value using the javascript: scheme, including whitespace or control characters. Clicking the link can execute JavaScript in the application context. The vulnerability was fixed by normalizing values and blocking unsafe schemes.
