CVE-2026-47187

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...

CVE-2026-47187

Prior to sshfs 3.7.6, the transform_symlink() mitigation returns early at sshfs.c:2181 without handling relative symlink targets, while sshfs_readlink() (sshfs.c:2234–2236) copies server-supplied targets to the kernel. A rogue SFTP server can thus direct local tools (cp, rsync, editors) to read o...

CVE-2026-49255 electerm: Command Injection in File System Operations (rmrf, mv, cp)

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.11.11, electerm constructs operating system commands in src/app/lib/fs.js by interpolating untrusted file paths into the rmrf, mv, and cp functions. A malicious SSH or SFTP server can provide a...

CVE-2026-49255

In electerm versions prior to 3.11.11, the rmrf(), mv(), and cp() functions in src/app/lib/fs.js interpolate untrusted file paths into shell command strings without escaping metacharacters. A malicious SSH/SFTP server can supply filenames like file"$(touch /tmp/pwned)" to break out of quotes and ...

USN-8093-2 libssh vulnerability

USN-8093-1 fixed a vulnerability in libssh. This update provides the corresponsing fix for Ubuntu 26.04 LTS. Original advisory details: It was discovered that libssh incorrectly performed bounds checking when processing SFTP extensions. If a client application queried extension data out of bounds...

CVE-2026-62598

Vulnerability in the Oracle Hyperion Calculation Manager product of Oracle Hyperion component: Security. The supported version that is affected is 11.2.25.0.000. Difficult to exploit vulnerability allows low privileged attacker with network access via SFTP to compromise Oracle Hyperion Calculatio...

GHSA-6C8M-Q6G9-VRW3 Lemur: Authenticated low-privilege users can read plaintext destination credentials (SFTP password / private-key passphrase) via the destinations API

Summary Lemur's destination read endpoints -- GET /api/1/destinations and GET /api/1/destinations/ -- return the full set of stored plugin option values to any authenticated user, with no authorization check and no redaction of secret-bearing options. The sibling write endpoints POST/PUT/DELETE a...

CVE-2026-71307 Lemur: Authenticated low-privilege users can read plaintext destination credentials (SFTP password / private-key passphrase) via the destinations API

Lemur manages TLS certificate creation. Prior to 1.9.3, GET /api/1/destinations and GET /api/1/destinations/ relied only on authentication while sibling write handlers required adminpermission. DestinationOutputSchema returned raw options and copied them into pluginOptions without redacting...

CVE-2026-71307

In Lemur before 1.9.3, GET /api/1/destinations endpoints required only basic authentication, allowing low-privilege users to read plaintext SFTP passwords and private-key passphrases stored by the sftp-destination plugin. CVSS 7.7 HIGH (network, low complexity). Fixed in 1.9.3 by requiring admin ...

libssh: libssh: denial of service via oversized SFTP read length

A flaw was found in libssh. A remote authenticated client can issue SSHFXPREAD requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests...

libssh: libssh: stack buffer overflow in SFTP server longname construction

A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead ...

Important: Red Hat Security Advisory: libssh security update

An update for libssh is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from t...

libssh: libssh: denial of service via SFTP responses with unknown request IDs

A flaw was found in libssh. A malicious SFTP server can send responses for unknown request IDs that libssh clients keep queued indefinitely, causing unbounded memory growth and client-side denial of service...

CVE-2026-54336

JumpServer is an open source bastion host and an operation and maintenance security audit system. From 4.8.0 until 4.10.17, an authenticated user with SFTP permission to an authorized asset can submit crafted traversal paths through the KoKo Web Terminal SFTP feature, causing AssetDir.GetRealPath...
