要点
- CVE-2026-33728 は com.datadoghq:dd-java-agent, dd-trace-java (datadog) に影響する深刻度「緊急」 (CVSS 9.8) の脆弱性です。
- 今後30日間に悪用される確率（EPSS）：0.71%（全脆弱性の 53.6% より高い）。
- 対処：1.60.3 以降に更新してください。
概要
In versions of dd-trace-java prior to 1.60.3, the RMI instrumentation registered a custom endpoint that deserialized incoming data without applying serialization filters. On JDK version 16 and earlier, an attacker with network access to a JMX or RMI port on an instrumented JVM could exploit this to potentially achieve remote code execution. All three of the following conditions must be true to exploit this vulnerability:
- dd-trace-java is attached as a Java agent (
-javaagent) on Java 16 or earlier
- A JMX/RMI port has been explicitly configured via
-Dcom.sun.management.jmxremote.port and is network-reachable
- A gadget-chain-compatible library is present on the classpath
Impact
Arbitrary remote code execution with the privileges of the user running the instrumented JVM.
Recommendation
- For JDK >= 17: No action is required, but upgrading is strongly encouraged.
- For JDK >= 8u121 < JDK 17: Upgrade to dd-trace-java version 1.60.3 or later.
- For JDK < 8u121 and earlier where serialization filters are not available, apply the workaround described below.
Workarounds
Set the following environment variable to disable the RMI integration: DD_INTEGRATION_RMI_ENABLED=false

NVD の説明
dd-trace-java is a Datadog APM client for Java. In versions of dd-trace-java 0.40.0 through prior to 1.60.2, the RMI instrumentation registered a custom endpoint that deserialized incoming data without applying serialization filters. On JDK version 16 and earlier, an attacker with network access to a JMX or RMI port on an instrumented JVM could exploit this to potentially achieve remote code execution. All three of the following conditions must be true to exploit this vulnerability: First, dd-trace-java is attached as a Java agent (`-javaagent`) on Java 16 or earlier. Second, a JMX/RMI port has been explicitly configured via `-Dcom.sun.management.jmxremote.port` and is network-reachable, Third, a gadget-chain-compatible library is present on the classpath. For JDK >= 17, no action is required, but upgrading is strongly encouraged. For JDK >= 8u121 < JDK 17, upgrade to dd-trace-java version 1.60.3 or later. For JDK < 8u121 and earlier where serialization filters are not available, apply the workaround. The workaround is to set the following environment variable to disable the RMI integration: `DD_INTEGRATION_RMI_ENABLED=false`.
