Prior to version 3.7.6, a rogue SFTP server can return absolute symlink targets or relative targets containing parent-directory components that SSHFS passes through FUSE for resolution by the client kernel against the local filesystem. The documented transform_symlinks mitigation does not contain relative targets because transform_symlink() returns early at sshfs.c:2181, while sshfs_readlink() at sshfs.c:2234 to sshfs.c:2236 otherwise copies the server-supplied link target to the kernel. A victim or victim-side tool that follows such a link through ordinary operations such as cp, rsync, backup tooling, or an editor can disclose readable local files back to the server or write server-controlled content to writable local files, potentially including startup or scheduled-task files. This issue is fixed in version 3.7.6.","published":"2026-08-19T15:17:05.310","modified":"2026-08-19T15:17:05.310","cvss":{"score":9.3,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/libfuse/sshfs/commit/bcd132f17ccf1b8592a229df797c9b08883fec26","label":"libfuse/sshfs@bcd132f"},"references":[{"type":"WEB","url":"https://github.com/libfuse/sshfs/commit/bcd132f17ccf1b8592a229df797c9b08883fec26"},{"type":"WEB","url":"https://github.com/libfuse/sshfs/pull/361"},{"type":"WEB","url":"https://github.com/libfuse/sshfs/releases/tag/sshfs-3.7.6"},{"type":"WEB","url":"https://github.com/libfuse/sshfs/security/advisories/GHSA-pjv6-2c3f-r357"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T15:17:05.310"}}
