UnverifiedThe core security risk of SSH agent forwarding is that once a remote host is compromised, an attacker can use the forwarded agent socket to impersonate the user and access other systems without ever touching the private key itself63% similarUnverifiedNextcloud's Brute-force protection mechanism records failed login attempts from the same IP, and when the number of failures exceeds a threshold within a short period it applies request throttling to that IP and logs it as suspicious activity63% similarUnverifiedLong-term holding of shell sessions on the server side involves resource consumption and security boundaries—if the agent has a vulnerability, an attacker could potentially take over the session without re-authenticating.62% similarUnverifiedIn 2023, multiple NPM packages were found to contain malicious code that automatically exfiltrated users' SSH keys and AWS credentials upon installation.62% similarUnverifiedWhen a local process continuously makes requests using invalid credentials, the source IP is often resolved as 127.0.0.1 or a LAN private address, causing Nextcloud to mistakenly identify it as the machine attacking itself61% similar
