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。...

libvirt: swtpm privilege escalation via symlink following

BIT-RCLONE-2026-88016 rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, when backend/local runs with --links, a source .rclonelink object can plant a symlink in the destination and later directory metadata is applied through that path...

rsync: rsync: Arbitrary File Read via Symlink Following
