PYSEC-2026-298 Boxlite: Path Traversal Vulnerability Leads to Arbitrary File Write on the Host

Summary Boxlite is a sandbox service that allows users to create lightweight virtual machines Boxes and run OCI containers within them. Boxlite allows users to specify the OCI image used by containers in the sandbox. However, when processing tar entries in OCI images, Boxlite does not account for...

golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...

EUVD-2026-25020

A logic error in the ln utility of uutils coreutils allows the utility to dereference a symbolic link target even when the --no-dereference or -n flag is explicitly provided. The implementation previously only honored the "no-dereference" intent if the --force overwrite mode was also enabled. Thi...

PT-2026-34481

A vulnerability in the tail utility of uutils coreutils allows for the exfiltration of sensitive file contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting the...

CVE-2026-5958 Race Condition in GNU Sed

When sed is invoked with both -i in-place edit and --follow-symlinks, the function opennextfile performs two separate, non-atomic filesystem operations on the same path: 1. resolves symlink to its target and stores the resolved path for determining when output is written, 2. opens the original...

CVE-2026-34603

Tina is a headless content management system. Prior to version 2.2.2, @tinacms/cli recently added lexical path-traversal checks to the dev media routes, but the implementation still validates only the path string and does not resolve symlink or junction targets. If a link already exists under the...

GHSA-9PPJ-QMQM-Q256 node-tar Symlink Path Traversal via Drive-Relative Linkpath

Summary tar npm can be tricked into creating a symlink that points outside the extraction directory by using a drive-relative symlink target such as C:../../../target.txt, which enables file overwrite outside cwd during normal tar.x extraction. Details The extraction logic in...
