Aug 19, 2026SSHFS is a network filesystem client for connecting to SSH servers.CVE-2026-48711 · Other software · libfuse · reported by GitHubHigh 7
SSHFS is a network filesystem client for connecting to SSH servers. From version 1.4 until 3.7.6, SSHFS accepts a bracketed mount source such as [-oProxyCommand=CMD]:/path and find_base_path() removes the brackets, leaving a host value that begins with - and is passed directly to ssh as a command-line argument. When a caller also supplies a path-valued sftp_server, ssh treats the normalized host as an option and the server path as its destination, causing an injected ProxyCommand to execute locally before any connection or authentication succeeds. The attack requires a caller or wrapper that passes an attacker-controlled mount source to SSHFS with the required sftp_server configuration and results in arbitrary command execution as the user running SSHFS. This issue is fixed in version 3.7.6.

Aug 19, 2026SSHFS is a network filesystem client for connecting to SSH servers.CVE-2026-47187 · Other software · libfuse · reported by GitHubCritical 9.3
SSHFS is a network filesystem client for connecting to SSH servers. 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.

Mar 20, 2026libfuse is the reference implementation of the Linux FUSE.CVE-2026-33179 · Other software · libfuse · reported by GitHubMedium 5.5
libfuse is the reference implementation of the Linux FUSE. From version 3.18.0 to before version 3.18.2, a NULL pointer dereference and memory leak in fuse_uring_init_queue allows a local user to crash the FUSE daemon or cause resource exhaustion. When numa_alloc_local fails during io_uring queue entry setup, the code proceeds with NULL pointers. When fuse_uring_register_queue fails, NUMA allocations are leaked and the function incorrectly returns success. Only the io_uring transport is affected; the traditional /dev/fuse path is not affected. PoC confirmed with AddressSanitizer/LeakSanitizer. This issue has been patched in version 3.18.2.

Mar 20, 2026libfuse is the reference implementation of the Linux FUSE.CVE-2026-33150 · Other software · libfuse · reported by GitHubHigh 7.8
libfuse is the reference implementation of the Linux FUSE. From version 3.18.0 to before version 3.18.2, a use-after-free vulnerability in the io_uring subsystem of libfuse allows a local attacker to crash FUSE filesystem processes and potentially execute arbitrary code. When io_uring thread creation fails due to resource exhaustion (e.g., cgroup pids.max), fuse_uring_start() frees the ring pool structure but stores the dangling pointer in the session state, leading to a use-after-free when the session shuts down. The trigger is reliable in containerized environments where cgroup pids.max limits naturally constrain thread creation. This issue has been patched in version 3.18.2.

FUSE, possibly 2.8.5 and earlier, allows local users to create mtab entries with arbitrary pathnames, and consequently unmount any filesystem, via a symlink attack on the parent directory of the mountpoint of a FUSE filesystem, a different vulnerability than CVE-2010-0789.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
