Linux Distros 未修补的漏洞：CVE-2026-101917
high Nessus 插件 ID 351365
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- PyJWT 是 JSON Web Token 标准的 Python 实现。之前 2.14.0的 PyJWT get_signing_key_from_jwt会受到影响，因为未知 kid 错过了没有负缓存或最小刷新间隔的强制刷新。当未经身份验证的标记反复使用缓存的 JWKS 中不存在的相同未知子项或不同的子项值时，便会发生这种情况。因此，每次缓存缺失都会导致 PyJWKClient 刷新 JWKS。因此，攻击者流量可放大对已配置 JWKS 端点的出站请求。此问题已在 2.14.0 版本中修复。(CVE-2026-101917)
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
