Arista Networks EOS: secrets in logs

Medium6.0CVE-2026-73465 · Published Sep 15, 2026 · updated Sep 17, 2026

On affected platforms running Arista EOS, under certain circumstances plaintext private keys 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.
