CVE-2026-9547
A vulnerability exists in libcurl where applications performing transfers via SCP:// or SFTP:// using the CURLOPT_SSH_KEYFUNCTION callback may silently accept untrusted servers. This occurs because the callback mechanism fails to reject a host key type that differs from the specific key type reco...
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...

CVE-2026-12064
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...

libssh2: libssh2: Information disclosure and denial of service via crafted SFTP response
A flaw in libssh2's sftpsymlink function allows a malicious SSH server or man-in-the-middle attacker to trigger an out-of-bounds heap read via a crafted SSHFXPNAME response. This can disclose heap memory contents or crash the application, causing a denial of service DoS...

Astra Linux – Vulnerability in libssh
A flaw was discovered in libssh, where a malicious SFTP SSH File Transfer Protocol server can exploit this by sending a malformed ‘longname’ field within an SSHFXPNAME message during a file listing operation. This missing null check can lead to reading beyond the allocated memory on the heap. Thi...
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...
curl: curl: Man-in-the-middle attack via SSH host key bypass
A flaw was found in curl. When a libcurl-based application uses SCP:// or SFTP:// for transfers and employs the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This occurs if the server's host key type differs from the one stored in the knownhosts file. The callback...
