Technical details
A stored Cross-Site Scripting (XSS) vulnerability exists in Pivotick versions up to and including 1.4.0. The root cause is the direct interpolation of 'data.label' and 'data.description' from graph data into the innerHTML of modal headers within 'InspectNodeModal.ts' and 'EditNodeModal.ts'. An attacker who can supply or modify the underlying graph data can inject malicious JavaScript. The payload executes when a victim opens the affected node's inspect or edit modal. The issue has been patched in later commits by switching from HTML interpolation to using 'textContent' for rendering these fields.
