CVE-2026-47187 is a critical symlink handling flaw in sshfs, affecting versions up to and including 3.7.5. When mounted against a rogue or untrusted SFTP server, sshfs passes server-supplied symlink targets to the kernel unchanged. Those targets may be absolute paths or relative traversal paths such as '../../../'. The kernel VFS then resolves the symlink on the client’s local filesystem rather than confining resolution to the remote filesystem view exposed through the sshfs mount. As a result, ordinary file operations performed through the mountpoint can escape the intended remote directory context and access local client files. The issue is classified as CWE-59, Improper Link Resolution Before File Access.
