Uncontrolled Recursion

Overview MessagePack is a MessagePackMsgPack Serializer for C.NET, .NET Core, Unity, Xamarin. Affected versions of this package are vulnerable to Uncontrolled Recursion in the DynamicUnionResolver.BuildDeserialize process. An attacker can cause a process crash by providing a specially crafted uni...

Uncontrolled Recursion

Overview MessagePack is a MessagePackMsgPack Serializer for C.NET, .NET Core, Unity, Xamarin. Affected versions of this package are vulnerable to Uncontrolled Recursion in the JSON conversion process. An attacker can cause the application to exhaust the process stack and terminate unexpectedly by...

MessagePack-CSharp: JSON conversion APIs can recurse without consistent depth enforcement

Summary 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 deserialization. Three related issues are covered by this advisory: 1...

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

Summary 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...

CVE-2026-11999

CVE-2026-11999 affects wolfSSL when built with --enable-opensslextra. The X509_verify_cert() path-depth exhaustion in wolfSSL_X509_verify_cert() can allow an attacker-controlled certificate to be accepted if the caller supplies untrusted intermediates and the chain depth exceeds the verifier’s ma...
