CVE-2025-61984 (GCVE-0-2025-61984)

Vulnerability from cvelistv5 – Published: 2025-10-06 00:00 – Updated: 2025-11-11 14:50

Summary

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. (A configuration file that provides a complete literal username is not categorized as an untrusted source.)

Severity ?

3.6 (Low)
