Vulnerability Title
xkeys Seal encryption used fixed key for all encryption
Vulnerability Description
NATS.io is a high performance open source pub-sub distributed communication technology, built for the cloud, on-premise, IoT, and edge computing. The cryptographic key handling library, nkeys, recently gained support for encryption, not just for signing/authentication. This is used in nats-server 2.10 (Sep 2023) and newer for authentication callouts. In nkeys versions 0.4.0 through 0.4.5, corresponding with NATS server versions 2.10.0 through 2.10.3, the nkeys library's `xkeys` encryption handling logic mistakenly passed an array by value into an internal function, where the function mutated that buffer to populate the encryption key to use. As a result, all encryption was actually to an all-zeros key. This affects encryption only, not signing. FIXME: FILL IN IMPACT ON NATS-SERVER AUTH CALLOUT SECURITY. nkeys Go library 0.4.6, corresponding with NATS Server 2.10.4, has a patch for this issue. No known workarounds are available. For any application handling auth callouts in Go, if using the nkeys library, update the dependency, recompile and deploy that in lockstep.

Vulnerability Title
NATS Server 安全漏洞
Vulnerability Description
NATS Server是一款开源消息系统。该系统主要用于云原生应用、物联网消息传递和微服务架构等。 NATS Server 2.10.0 到2.10.3版本、nkeys 0.4.0 到 0.4.5版本存在安全漏洞，该漏洞源于nkeys 库的xkeys加密处理逻辑错误地将数组按值传递到内部函数中，改变了缓冲区要使用的加密密钥，导致所有加密实际上都是全零密钥。
