CVE-2026-48513

CVE-2026-48513 (MessagePack-CSharp) affects the MessagePack serializer for C#. The vulnerability arises in runtime-generated union deserializers created by DynamicUnionResolver, which did not call DepthStep(ref reader) or decrement reader.Depth during recursive deserialization and skip paths. As ...

CVE-2026-48513 MessagePack-CSharp: DynamicUnionResolver generated deserializers miss depth enforcement

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, runtime-generated union deserializers emitted by DynamicUnionResolver do not call MessagePackSecurity.DepthStepref reader and do not decrement reader.Depth around recursive deserialization and skip paths. This means...

CVE-2026-48515 MessagePack-CSharp: Multi-dimensional array formatters allocate from unchecked dimensions

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, MessagePack-CSharp's multi-dimensional array formatters read dimension lengths directly from the payload and allocate T,, T,,, or T,,, before validating that the dimension product matches the encoded element count. T...

Oj: Negative-Size memcpy in Oj::Parser create_id Attribute Handling

Summary Oj::Parserparse in usual mode with createid enabled is vulnerable to heap corruption via a negative-size memcpy. When a JSON object key is exactly 65,535 bytes long, an integer truncation in formattr usual.c:63 converts the length to -1 before passing it to memcpy. This causes memcpy to...
