CVE-2026-107574

Progressive Robot hMailServer is vulnerable to a Denial of Service (DoS) attack due to inefficient algorithmic complexity (O(N^2)) in its JSON reader. The component fails to efficiently handle duplicated member names, causing significant processing delays: a 4 MB object can take 300 seconds to pr...

Dasel: Unbounded recursion in JSON and XML readers causes unrecoverable stack-overflow DoS

Summary dasel's JSON and XML readers parse nested structures with unbounded recursion, one native stack frame per nesting level, with no depth guard. A small sub-10 MB, deeply nested document drives the Go runtime past its goroutine stack limit and triggers a fatal error: stack overflow. This is...

CVE-2026-59168

The Dasel command-line tool and library (versions 3.0.0 through 3.11.0 ) are vulnerable to an unrecoverable Denial of Service (DoS) due to unbounded recursion in the JSON and XML readers. The decodeValue, decodeObject, and decodeArray functions in parsing/json/json_reader.go, along with parseElem...

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...

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...

llama_index JSON Reader DoS

The vulnerability of the llamaindex component of the JSON data reading class, implemented through JSONReader tokens, is related to an uncontrolled recursion. Exploiting this vulnerability could allow a malicious actor to cause service failures...

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...
