CVE-2026-73466CVE-2026-73466

On affected platforms running Arista EOS, under certain circumstances user passwordss may be written in clear text to log files during operations when specialized non-standard debugging trace levels are explicitly enabled. To exploit these vulnerabilities, a malicious actor must already possess authenticated local administrative access to the device shell, and specialized non-standard debugging trace levels must be explicitly enabled. This issue was discovered internally by Arista, and the company is not aware of any malicious exploitation of this vulnerability in customer networks.
