Vulnerability Title
N/A
Vulnerability Description
A flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided signatures, potentially leaking timing information proportional to the number of matching bytes. Under certain threat models where high-resolution timing measurements are possible, this behavior could be exploited as a timing oracle to infer HMAC values. Node.js already provides timing-safe comparison primitives used elsewhere in the codebase, indicating this is an oversight rather than an intentional design decision. This vulnerability affects **20.x, 22.x, 24.x, and 25.x**.

Node.js 安全漏洞
Vulnerability Description
Node.js是Node.js开源的一个开源、跨平台的 JavaScript 运行时环境。 Node.js 20.x版本、22.x版本、24.x版本和25.x版本存在安全漏洞，该漏洞源于HMAC验证使用非恒定时间比较，可能泄露与匹配字节数成比例的时间信息，进而可能被用作时序预言机。
