GHSA-3M6Q-H5GJ-7MRW Gitea has insecure default SSH settings

Summary The built-in SSH server currently advertises a number of key exchange, MAC, and host key algorithms that are considered weak or broken. The defaults should be tightened so a fresh installation passes a baseline SSH security audit out of the box. Details Running ssh-audit against a default...

CVE-2025-13914

A Key Exchange without Entity Authentication vulnerability in the SSH implementation of Juniper Networks Apstra allows a unauthenticated, MITM attacker to impersonate managed devices. Due to insufficient SSH host key validation an attacker can perform a machine-in-the-middle attack on the SSH...

JLSEC-2026-72

A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. Fo...

curl: Missing server identity policy enforcement in SSH connection reuse allows host key verification bypass via pool poisoning

Missing server identity policy enforcement in SSH connection reuse allows host key verification bypass via pool poisoning --- Summary sshconfigmatches in lib/url.c decides whether an existing SSH connection can be reused by a new transfer handle. It checks client key paths rsa, rsapub but never...

curl: Bypassing Strict SSH Server Verification via Connection Pool Reuse in libcurl

Summary There is a logic flaw in how libcurl manages its connection pool for SSH protocols SFTP/SCP. When evaluating an existing connection for reuse, sshconfigmatches in lib/url.c fails to compare server identity verification policies. By ignoring CURLOPTSSHKNOWNHOSTS, CURLOPTSSHHOSTPUBLICKEYMD5...

CVE-2026-33724

n8n is an open source workflow automation platform. Prior to version 2.5.0, when the Source Control feature is configured to use SSH, the SSH command used for git operations explicitly disabled host key verification. A network attacker positioned between the n8n instance and the remote Git server...

Authorization Bypass Through User-Controlled Key

Overview n8n is a n8n Workflow Automation Tool Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key in the Source Control feature when configured to use SSH, as the SSH command disables host key verification. An attacker can intercept repository dat...
