CVE-2026-14361

CVE-2026-14361 Consul Template 的 writeToFile 辅助函数直接打开操作者提供的目标路径，并跟随被链接的路径组件，从而使渲染输出能够逃逸预期目录并覆盖已存在的文件。 简介 我在审查 HashiCorp Consul Template 时发现了这个问题，当时脑海中有一个直接的文件系统安全问题： 如果writeToFile 收到的路径看似位于预期目录之内，它是否会验证文件系统实际将数据写入何处？ 在本例中，答案是否定的。 writeToFile 模板辅助函数通过 os.Create 或 os.OpenFile 直接打开用户提供的最终路径。...

通过 CVE-2017-1002101 实现 Kubernetes 逃逸示例 描述 在了解到这个问题并参考此指南后，我想进一步探索。该仓库包含几个 Pod 部署和辅助 Shell 脚本，以最简单的方式演示了攻击机制，使 Kubernetes 管理员和运维人员能够充分理解其严重性和潜在风险。您必须是已认证用户，或者能够在创建 Pod 时控制其 spec/template，因此这种逃逸不太可能以匿名方式发生，除非与其他攻击（如这个）结合使用。 快速解释 当 Kubelet 挂载卷/密钥/配置映射等时，它会错误地跟随卷内部的符号链接，访问到本应限制范围之外的位置。由于 Kubelet 以 ro...

CVE-2026-77159

A symlink-following flaw was found in libvirt's qemuTPMEmulatorPrepareHost function. The function uses a path-based chown on the swtpm logfile without checking for symbolic links. A local attacker with access to the swtpm account can replace the logfile with a symlink, causing libvirtd running as...

EUVD-2026-76070

Hugo is a static site generator. In versions after v0.123.0 and before v0.165.0, symlinks in parent directories were not dropped during direct resource lookups, allowing path confinement to be bypassed. An attacker who can place — or who convinces a site author to place — a symlink inside a mount...
