Spring Micrometer
Monthly
Line-protocol injection and log spoofing in Spring Micrometer's StatsD and LoggingMeterRegistry components allow network-reachable attackers to forge arbitrary metrics and log entries by embedding newline characters into user-supplied strings that flow unvalidated into meter names, tag keys, or tag values. Affected deployments span the 1.9.x through 1.17.x release lines of io.micrometer:micrometer-registry-statsd and io.micrometer:micrometer-core when the Datadog or Etsy StatsD flavor is active, or when LoggingMeterRegistry is in use. No public exploit has been identified at time of analysis, though the integrity-focused impact carries real risk for organizations whose incident-response workflows depend on Micrometer-sourced telemetry.
