As a result, an attacker positioned on the network path can intercept credentials in transit. Captured credentials could allow the attacker to authenticate as a cluster node or service account, enabling further unauthorized access, lateral movement, or system compromise.\n\n## Affected\n\n- `log_server < 2024`\n- `log_server = 2024`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `log_server 2024`","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
