CVE-2025-65945-poc
CVE-2025-65945: node-jws 签名绕过 这是 node-jws 库中签名验证绕过漏洞的概念验证。该漏洞允许攻击者在服务器从用户可控数据派生 HMAC 密钥时伪造有效的 JWT。 漏洞原理是什么？ jws.createVerify 函数在使用 HMAC 算法时，不会验证是否确实提供了密钥。如果你的应用程序根据 JWT 中的某些内容（如 kid 头）查找密钥，并且查找失败，那么你最终可能会使用空密钥进行验证。 攻击者可以利用这一点： 1. 发送一个包含不存在于数据库中的虚假密钥 ID 的 JWT 2. 使用空字符串作为密钥签署其恶意负载 3. 服务器的查找返回...

CVE-2026-102266 PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation
PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.fromjwk is affected because PyJWK verification path used the decoded key without applying preparekey validation. This occurs when a trusted JWK Set contains an oct entry with an empty k value. As...
