CVE-2026-48514 MessagePack-CSharp: Unity unsafe blit formatter allocates from unbounded byte length

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, UnsafeBlitFormatterBase.Deserialize reads an attacker-controlled byteLength from an extension payload and allocates an array based on that value before validating it against the extension header length or remaining...

GHSA-43X2-G84Q-FMQX OpenDJ Pre-Auth RCE via Java Deserialization in JMX RMI

Summary Description A Deserialization of Untrusted Data CWE-502 issue in OpenDJ's JMX RMI connector allows an unauthenticated remote attacker to deserialize arbitrary Java objects on the server. The vulnerability exists because the platform reads and processes attacker-controlled bytes prior to...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the JMX RMI connector. An attacker can execute arbitrary code on the server by sending specially crafted serialized Java objects prior to authentication. Note: This is only exploitable if the JMX...

CVE-2025-71358

CVE-2026-48517

CVE-2026-48517 affects MessagePack-CSharp (MessagePack for C#). The vulnerability arises because typeless deserialization’s safety check (ThrowIfDeserializingTypeIsDisallowed) only validates the outer type name and does not recursively inspect inner types such as array element types or generic ty...

CVE-2026-48517 MessagePack-CSharp: Typeless deserialization type restrictions do not recurse into arrays or generic arguments

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, MessagePack-CSharp's typeless deserialization includes MessagePackSerializerOptions.ThrowIfDeserializingTypeIsDisallowedType as a safety check for dangerous types. The default implementation checks the outer type nam...
