24th percentile - higher than 24% of all known CVEs

Kener 4.0.0 before 4.1.6 contains an information disclosure vulnerability that allows unauthenticated attackers to retrieve hidden or inactive monitor data by querying dashboard API handlers lacking visibility filters. Attackers can supply a known or guessed monitor tag to endpoints such as monitor-bar and monitor-latency-chart to obtain names, descriptions, status, uptime history and latency.

An unauthenticated attacker can access internal monitoring data that should be hidden, potentially revealing information about the organization's infrastructure. This may facilitate further reconnaissance attacks.

Update Kener to version 4.1.6 or later. Until then, consider restricting access to dashboard API endpoints.
