CVE-2026-59295

CVE-2026-59295 affects applications using MicrometerHttpClientInterceptor to instrument Apache HttpAsyncClient (4.x or 5.x). When asynchronous requests fail before receiving a response—such as connection resets or timeouts—the per-request tracking state is never released, causing an unbounded mem...

PT-2026-80797

Name of the Vulnerable Software and Affected Versions Apache HttpAsyncClient versions 4.x Apache HttpAsyncClient versions 5.x Description Usage of Apache HttpAsyncClient via MicrometerHttpClientInterceptor can lead to unbounded memory leaks when asynchronous requests fail before a response is...

CRLF Injection

Overview Affected versions of this package are vulnerable to CRLF Injection through DatadogStatsdLineBuilder, EtsyStatsdLineBuilder, and the Printer in LoggingMeterRegistry. An attacker can spoof metrics or log entries by supplying meter names, tag keys, or tag values containing \n or \r, causing...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the contextWithBaggage parsing path in io.micrometer.tracing.brave.bridge.W3CPropagation. An attacker can exhaust CPU and heap by sending a request with a W3C baggage header...

CVE-2026-59296

Using untrusted, non-normalized input as-is for metrics data such as metric names, tag keys, or tag values is a dangerous antipattern that general-purpose instrumentation should never perform. Micrometer 1.17.0 Micrometer 1.16.0 - 1.16.6 Micrometer 1.15.0 - 1.15.12 Micrometer 1.14.0 - 1.14.16...

EUVD-2026-63885

Using untrusted, non-normalized input as-is for metrics data such as metric names, tag keys, or tag values is a dangerous antipattern that general-purpose instrumentation should never perform. When such unsafe instrumentation is used, the application becomes vulnerable to injection and spoofing...

CVE-2026-59296

CVE-2026-59296 affects io.micrometer:micrometer-registry-statsd and io.micrometer:micrometer-core , which do not sanitize newline characters (\n, \r) in metric names, tag keys, or tag values by default. When an application instruments meters using user-controlled, unvalidated input , an attacker ...
