CVE-2026-9547 SSH improper host validation

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...

curl: curl: SSH host verification bypass when using schemeless URLs with SFTP/SCP

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...

CVE-2026-40987

A flaw was found in Spring Integration. A malicious or compromised FTP File Transfer Protocol, SFTP SSH File Transfer Protocol, or SMB Server Message Block server can exploit this vulnerability. This allows the server to write arbitrary files with attacker-controlled content to any location on th...

CVE-2026-58056 RustDesk - FileTransfer Session Authorization Scope Bypass

RustDesk gates incoming control messages on per-capability flags rather than on the session's authorized connection type, and a file-transfer session does not clear those flags. A peer holding only a valid FileTransfer authorization can inject keyboard and mouse input and reach the unguarded...
