Vulnerability Title
Pivotick - Stack Exhaustion Denial of Service via Deep or Cyclic Graph Data
Vulnerability Description
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.

Vulnerability Title
Pivotick 资源管理错误漏洞
Vulnerability Description
Pivotick Pivotick是Pivotick组织开源的一款企业应用软件。 Pivotick 1.4.0及之前版本存在资源管理错误漏洞,该漏洞源于不受控制的递归,在处理用户提供的图形和节点数据时,图算法递归遍历边且JSON查看器递归处理节点数据结构,可能导致攻击者利用特制图形导致JavaScript调用栈耗尽,造成客户端拒绝服务。
