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-2026-58056 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...

CVE-2026-58056

RustDesk is affected by a session-authorization scope bypass in FileTransfer sessions. The root cause is gating incoming control messages on per-capability flags rather than the session’s authorized connection type; a peer with only valid FileTransfer authorization can inject keyboard/mouse input...

CVE-2026-55189 RustFS: FTP frontend skips IAM authorization on object reads

RustFS is a distributed object storage system built in Rust. From 1.0.0-alpha.1 until 1.0.0-beta.9, when the FTP frontend is enabled, the FTP read and probe handlers dispatch directly to the storage backend without ever calling the IAM authorization function that the FTP write/list handlers and t...

CVE-2026-55189

RustFS (distributed object storage in Rust) contains a vulnerability from 1.0.0-alpha.1 through 1.0.0-beta.9 where enabling the FTP frontend lets FTP read and probe handlers bypass the IAM authorization function, allowing authenticated users to read objects and probe buckets regardless of IAM pol...

CVE-2026-49486 Apache Airflow FTP provider: FTP Provider does not protect FTPS data channel (missing PROT_P)

The Apache Airflow FTP provider's FTPSHook.getconn created an ftplib.FTPTLS connection but never called protp, so although the control channel was TLS-protected the data channel was transmitted in cleartext. Any deployment using FTPSHook or FTPSFileTransmitOperator to move files over FTPS exposed...

CVE-2026-49486

The CVE concerns the Apache Airflow FTP provider. The FTPSHook.get_conn() creates an ftplib.FTP_TLS connection but does not call prot_p(), leaving the data channel unencrypted even though the control channel is TLS-protected. This exposes file contents and credentials-in-transit to anyone who can...
