Vulnerability Title
MessagePack-CSharp: MessagePackReader.Skip can recurse without enforcing maximum object graph depth
Vulnerability Description
MessagePack for C# is a MessagePack serializer for C#. Prior to 2.5.301 and 3.1.7, MessagePackReader.TrySkip() recursively descends into nested arrays and maps without incrementing the reader depth or calling the configured depth checks. This bypasses MessagePackSecurity.MaximumObjectGraphDepth, the library's documented protection against deeply nested object graphs. Many generated and dynamic formatters call reader.Skip() when they encounter unknown map keys, unknown array members, ignored fields, or data that should be skipped for forward compatibility. A deeply nested value in one of these skipped positions can therefore cause unbounded recursion and an uncatchable StackOverflowException. This vulnerability is fixed in 2.5.301 and 3.1.7.

MessagePack-CSharp 资源管理错误漏洞
Vulnerability Description
MessagePack-CSharp MessagePack-CSharp是MessagePack-CSharp团队的一款消息序列化工具。 MessagePack-CSharp 2.5.301之前版本和3.1.7之前版本存在资源管理错误漏洞,该漏洞源于MessagePackReader.TrySkip()在递归处理嵌套数组和映射时未增加读取器深度或调用配置的深度检查,绕过了MaximumObjectGraphDepth限制,可能导致不可捕获的StackOverflowException。
