CVE-2026-D0cker

CVE-2026-Pending: 通过 runC maskPaths 漏洞实现容器逃逸 严重级别: 严重 CVSS 9.8 组件: opencontainers/runc libcontainer 漏洞类型: CWE-59: 在访问文件前未正确解析链接（'链接跟随'） 🚨 执行摘要 runc 的 maskPaths 函数存在一个严重漏洞。当在容器内屏蔽敏感路径（如 /proc/kcore）时，runc 使用了 os.OpenFilepath, OPATH, 0 但没有添加 ONOFOLLOW 标志。这允许恶意容器进程将目标路径替换为指向敏感主机文件（例如...

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。...

rsync: rsync: Local Privilege Escalation via Symlink Following

A symlink-following vulnerability in rsync allows local attackers to redirect predictable output paths to arbitrary filesystem locations. When rsync runs with elevated privileges such as setuid or a privileged daemon, this enables arbitrary file overwrites and local privilege escalation...

rsync: rsync: Arbitrary File Read via Symlink Following

A flaw was found in rsync. A local attacker with low privileges can exploit a symlink following vulnerability in the handling of input configuration files, such as those specified by --files-from or --password-file. This allows the attacker to read arbitrary files accessible to the rsync daemon...

ALSA-2026:67463 Important: rsync security, bug fix, and enhancement update

The rsync utility enables the users to copy and synchronize files locally or across a network. Synchronization with rsync is fast because rsync only sends the differences in files over the network instead of sending whole files. The rsync utility is also used as a mirroring tool. Security Fixes:...

CVE-2026-89258

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...
