Summary Kopia's HTTP server, when started with --without-password , accepts unauthenticated requests to /api/v1/repo/exists. The handler forwards an attacker-supplied storage configuration to blob.NewStorage. For SFTP backends with externalSSH: true, that path constructs a process command line by...

GHSA-P4H8-56QP-HPGV SSH/SCP option injection allowing local RCE in @aiondadotcom/mcp-ssh
Impact A crafted hostAlias argument such as -oProxyCommand=... was passed to ssh/scp without an argument terminator. SSH interprets arguments starting with - as options regardless of position, so the option-injection caused SSH to execute the attacker-supplied ProxyCommand locally on the machine...
NewStart CGSL MAIN 7.02 : openssh Multiple Vulnerabilities (NS-SA-2026-0036)
The remote NewStart CGSL host, running version MAIN 7.02, has openssh packages installed that are affected by multiple vulnerabilities: - ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used. CVE-2025-61985 - ssh ...
MGASA-2026-0059 Updated openssh packages fix security vulnerabilities
ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. CVE-2025-61984...
