CVE-2026-48502

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, MessagePackReader.ReadDateTime can allocate stack memory based on an attacker-controlled MessagePack extension length. In the slow path for timestamp extension parsing, the computed tokenSize includes the extension...

CVE-2026-48512

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, MessagePack-CSharp's JSON conversion helpers contain multiple recursion paths that do not consistently enforce a depth limit. These paths are in the JSON conversion component rather than normal typed MessagePack...

CVE-2026-48502

MessagePack-CSharp contains a Denial of Service vulnerability in MessagePackReader.ReadDateTime() where a stack allocation is driven by attacker-controlled extension length. In the slow path, tokenSize includes the extension body length and is used in a stackalloc before the extension length is v...

CVE-2026-48502 MessagePack-CSharp: Denial of service vulnerabilities can swamp the CPU or crash the process with stack and heap overflows

CVE-2026-48506

The CVE-2026-48506 entry concerns MessagePack-CSharp: MessagePackReader.TrySkip() can recurse without incrementing depth checks, bypassing MaximumObjectGraphDepth and risking unbounded recursion leading to StackOverflow. Affected: MessagePack-CSharp (reader Skip usage in nested arrays/maps). Root...

CVE-2026-48506 MessagePack-CSharp: MessagePackReader.Skip can recurse without enforcing maximum object graph depth

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...

CVE-2026-48512

CVE-2026-48512 affects MessagePack-CSharp. The JSON conversion helpers in MessagePack-CSharp allowed recursive processing without a consistent depth limit, enabling attacker-controlled input to exhaust the process stack and trigger a StackOverflowException. This occurs in the JSON conversion path...

dotnet: ASP.NET Core: Denial of Service via uncontrolled resource consumption

A flaw was found in ASP.NET Core SignalR and Blazor Server. A remote attacker could send a specially crafted MessagePack payload containing deeply nested arrays that trigger excessive recursion and cause a stack overflow. This issue may result in application termination and a denial of service...

CVE-2026-48712

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.6.1 and 8.4.1, protobufjs could recurse without a depth limit while converting decoded messages to plain objects or JSON. This affected generated toObject conversion and the custom google.protobuf.Any JSON conversio...
