Detailsinfo

A vulnerability was found in Pivotick up to 1.4.0. It has been declared as problematic. This vulnerability affects an unknown code of the component Graph Traversal/JSON Viewer. The manipulation with an unknown input leads to a recursion vulnerability. The CWE definition for the vulnerability is CWE-674. The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. As an impact it is known to affect availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-66920 since 07/28/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1499.

Applying the patch 66373141eb7892fc29a3b42cfb2c160af16765fe is able to eliminate this problem.
