CVE-2026-49451

The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. From 2.0.0-preview11 until 2.7.5 and 3.5.4, a small OpenAPI document containing a circular schema reference can cause proce...

CVE-2026-49451

The issue affects the OpenAPI.NET SDK used for OpenAPI document parsing in .NET. A circular schema reference in a small OpenAPI document can cause process termination via stack overflow when using public OpenAPI.NET reader APIs, applicable to both JSON and YAML paths. Affected versions range from...

Microsoft.OpenAPI: Circular schema references may terminate OpenAPI parsing

Impact A small OpenAPI document containing a circular schema reference can cause process termination through stack overflow in Microsoft.OpenApi. The issue affects OpenAPI document parsing through public OpenAPI.NET reader APIs and has been confirmed across both JSON and YAML reader paths. Affect...

CVE-2025-5302

A flaw was found in the JSONReader component of the llamaindex Python package, where the depthfirstyield function has no limit on the recursive number of times it is called. This vulnerability causes Python to reach its maximum recursive depth when parsing deeply nested JSON files. The program...

GHSA-7753-XRFW-CH36 LlamaIndex affected by a Denial of Service (DOS) in JSONReader

A denial of service vulnerability exists in the JSONReader component of the run-llama/llamaindex repository, specifically in version v0.12.37. The vulnerability is caused by uncontrolled recursion when parsing deeply nested JSON files, which can lead to Python hitting its maximum recursion depth...

Uncontrolled Recursion

Overview llama-index-core is an Interface between LLMs and your data Affected versions of this package are vulnerable to Uncontrolled Recursion via the JSONReader component. An attacker can cause excessive resource consumption and crash the process by submitting deeply nested JSON files...
