Summary
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.
Risk Assessment
An attacker could access victim information, modify application data, or perform actions using the victim's session.
Recommendation
Update Pivotick to a version containing the fix, which creates modal elements without embedding graph data in HTML and assigns labels via textContent.
Other vulnerabilities in Pivotick
See all- CVE-2026-67174Critical
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.
- CVE-2026-67173Medium
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.
- CVE-2026-66922Medium
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.
- CVE-2026-66921Medium
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.
- CVE-2026-66920High
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.
- CVE-2026-66918High
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.
- CVE-2026-66825Medium
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.
Original NVD description (English source)
Pivotick contains a cross-site scripting vulnerability in the inspect and edit node modals. Node labels and descriptions originating from graph data were interpolated directly into HTML used to construct the modal headers. An attacker able to supply or modify graph data could insert a malicious HTML or JavaScript payload into a node’s label or description. The payload would be parsed and executed in the application’s origin when a user opened the affected node’s inspect or edit modal. Successful exploitation could allow the attacker to access information available to the victim, modify application data, or perform actions using the victim’s active session. The vulnerability has been addressed by creating the modal elements without embedding graph data in HTML and assigning node labels and descriptions through textContent.
