GHSA-qhmf-xw27-6rqr: MessagePack-CSharp: Typeless deserialization type restrictions do not recurse into arrays or generic argumentsCVE-2026-48517 0 MessagePack-CSharp's typeless deserialization feature has a vulnerability where type restrictions do not recursively inspect array element types or generic type arguments. This allows an attacker to bypass outer-type blocklist checks by wrapping disallowed types inside arrays or generic containers. The issue affects applications that deserialize untrusted data using typeless serialization APIs. Fixes are available in versions 2.5.301 and 3.1.7. Users are advised to upgrade and avoid typeless deserialization of untrusted data or use explicit recursive allowlists.
