| CVE-2018-7749 | Cri | 0.57 | 9.8 | 0.02 | Mar 12, 2018 | The SSH server implementation of AsyncSSH before 1.12.1 does not properly check whether authentication is completed before processing other requests. A customized SSH client can simply skip the authentication step. | ||
| CVE-2026-54591 | Hig | 0.46 | 8.1 | 0.00 | Jul 8, 2026 | 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… | ||
| CVE-2026-45309 | Hig | 0.42 | 7.5 | 0.00 | Jul 17, 2026 | 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 2.23.0, AsyncSSH expands the OpenSSH-compatible AuthorizedKeysFile %u token in asyncssh/config.py,… | ||
| CVE-2023-48795 | Med | 0.39 | 5.9 | 0.93 | Dec 18, 2023 | The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently… | ||
| CVE-2023-46446 | Med | 0.37 | 6.8 | 0.01 | Nov 14, 2023 | An issue in AsyncSSH before 2.14.1 allows attackers to control the remote end of an SSH client session via packet injection/removal and shell emulation, aka a "Rogue Session Attack." | ||
| CVE-2026-54590 | Med | 0.31 | 5.9 | 0.00 | Jul 8, 2026 | AsyncSSH is a Python package which provides an asynchronous client and server implementation of the SSHv2 protocol on top of the Python asyncio framework. Version 2.23.0 contains an incomplete fix for CVE-2026-45309 in SSHServerConfig._set_tokens that blocks /, , and .. before… | ||
| CVE-2023-46445 | Med | 0.31 | 5.9 | 0.01 | Nov 14, 2023 | An issue in AsyncSSH before 2.14.1 allows attackers to control the extension info message (RFC 8308) via a man-in-the-middle attack, aka a "Rogue Extension Negotiation." |
