CVE-2026-54591 AsyncSSH: SCP Path Traversal to Arbitrary File Write
AsyncSSH is a Python package which provides an asynchronous client and server implementation of the SSHv2 protocol on top of the Python asyncio framework. Prior to 2.23.1, a malicious SSH server can write arbitrary files on the asyncssh SCP client's filesystem by sending filenames containing ../...

Relative Path Traversal
Overview Affected versions of this package are vulnerable to Relative Path Traversal via the scp process. An attacker can cause files to be placed outside the intended directory by crafting a copy operation between two remote destinations. Remediation A fix was pushed into the master branch but n...

PT-2026-56287
Name of the Vulnerable Software and Affected Versions OpenSSH versions prior to 10.4 Description The scp utility may place a file in the parent directory of the intended destination when performing a copy operation between two remote destinations. Recommendations Update to version 10.4 or later...
PYSEC-2026-1892 Salt preflight script could be attacker controlled
The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script wi...
CVE-2026-12064
A flaw was found in curl. When a user invokes curl with a schemeless URL and specifies SFTP SSH File Transfer Protocol or SCP Secure Copy Protocol as the default protocol, the tool layer fails to initialize critical SSH security options. This bypasses host verification, allowing curl to connect t...
USN-8514-1 openssh vulnerability
It was discovered that OpenSSH incorrectly handled file permissions when downloading files as root using the legacy scp protocol without the preserve-mode option. An attacker could use this to install setuid or setgid files on a system, possibly leading to privilege escalation...
CVE-2026-9547
When a libcurl-based application performs transfers via SCP:// or SFTP:// and utilizes the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for th...
CVE-2026-12064
CVE-2026-12064 describes an issue in curl where using a schemeless URL with --proto-default for SFTP/SCP causes the tool layer to skip SSH security configuration (notably CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256 and CURLOPT_SSH_KNOWNHOSTS ). The libcurl runtime honors the default protocol and proceeds ...
CVE-2026-12064 proto-default skips SSH verification
When a user invokes curl using a schemeless URL combined with --proto-default sftp or scp, a disconnect occurs between the tool layer and libcurl. The tool layer incorrectly infers the URL scheme, which erroneously bypasses the initialization of critical SSH security options like...
