Summary
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.
Risk Assessment
An attacker can access victim's information, manipulate graph data or application state, and perform actions with the victim's privileges, posing a serious risk to data confidentiality and integrity.
Recommendation
Apply the patch that changes string rendering to use textContent, requires explicit Element return for HTML rendering, and sanitizes SVG icon markup before DOM insertion.
Other vulnerabilities in Pivotick
See all- 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-2026-66919Medium
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.
- 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 DOM-based cross-site scripting vulnerability in its generic UI element resolution and icon-rendering utilities. The tryResolveHTMLElement function treated any resolved string as HTML markup by assigning it to a <template> element through innerHTML. Strings derived from untrusted graph properties or custom rendering callbacks could therefore introduce arbitrary HTML or SVG elements into the live document. The vulnerable function was used by multiple UI components, including headers, property panels, extra panels, and tooltips. Additionally, createIcon inserted caller-supplied svgIcon markup into a template without sanitization. An application integrating Pivotick and deriving icon markup from untrusted data could therefore expose a second script-execution path. An unauthenticated attacker able to provide a crafted graph, property value, rendering result, or SVG icon could execute JavaScript in another user's browser when the affected content is displayed or interacted with. Successful exploitation could allow the attacker to access information available to the victim, manipulate graph data or application state, and perform actions with the victim's privileges. The patch changes string rendering to use textContent, requiring callers to explicitly return an Element when HTML rendering is intended. It also sanitizes SVG icon markup before inserting it into the DOM.
