{"cve":"CVE-2026-33728","nvd":{"published":"2026-03-27T01:16:20.203","modified":"2026-06-17T10:37:59.980","status":"Analyzed","description":"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`.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["https://github.com/DataDog/dd-trace-java/releases/tag/v1.60.3","https://github.com/DataDog/dd-trace-java/security/advisories/GHSA-579q-h82j-r5v2"],"products":["datadog:dd-trace-java"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33728","score":0.00712,"percentile":0.53629,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-579q-h82j-r5v2","url":"https://osv.dev/vulnerability/GHSA-579q-h82j-r5v2","summary":"dd-trace-java: Unsafe deserialization in RMI instrumentation may lead to remote code execution","modified":"2026-06-09T12:00:12.397006306Z","packages":[{"ecosystem":"Maven","name":"com.datadoghq:dd-java-agent","purl":"pkg:maven/com.datadoghq/dd-java-agent","ranges":[">=0.40.0 <1.60.3"],"fixed":["1.60.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
