CVE-2026-40876

CVE-2026-40876 (goshs) describes an SFTP jail-escape due to a prefix-based path validation bug in the sftpserver.helper.go sanitizePath implementation. The code uses a raw string-prefix check to validate the target path against the configured root, which allows a sibling path (e.g., /tmp/goshsroo...

Zio has SubFileSystem Path Confinement Bypass via Unresolved `..` Segment

Summary SubFileSystem fails to confine operations to its declared sub path when the input path is /../ or equivalents /../, /..\. This path passes all validation but resolves to the root of the parent filesystem, allowing directory level operations outside the intended boundary. Affected Componen...

goshs is a SimpleHTTPServer written in Go. From 1.0.7 to before 2.0.0-beta.4, the SFTP command rename sanitizes only the source path and not the destination, so it is possible to write outside of the root directory of the SFTP. This vulnerability is fixed in 2.0.0-beta.4...

USN-8168-1: Rust vulnerability

It was discovered that tar-rs embedded in rustc incorrectly handled symlinks when unpacking a tar archive. If a user or automated system were tricked into processing a specially crafted tar archive, a remote attacker could use this issue to modify permissions of arbitrary directories outside the...

BIT-GOLANG-2026-32282 TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix

On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the ATSYMLINKNOFOLLOW flag, which Root.Chmod uses to...
