CVE-2026-66920

Pivotick contains an uncontrolled-recursion vulnerability when processing caller-supplied graph and node data. The affected graph algorithms recursively traversed graph edges, while the JSON viewer recursively processed each level of a node’s data structure. A specially crafted graph containing an excessively long path, deeply nested properties, or circular object references could therefore exhaust the JavaScript call stack when Pivotick calculates a layout or displays a node in the inspection modal. Successful exploitation may cause an uncaught exception, freeze the affected page, or crash the browser tab, resulting in a client-side denial of service. No confidentiality or integrity impact has been identified. The patch replaces the recursive graph traversals with iterative stack-based implementations and limits the reachability calculation to 1,000,000 edge traversals. It also limits JSON rendering to 64 levels and detects circular references before descending further into an object.
