In versions prior to 2.27.0, the RMI context propagation payload reader limits the number of context entries but does not limit the aggregate size of the strings read from the stream. An attacker who can reach an RMI endpoint on an instrumented JVM can send an oversized context propagation payload. This can cause excessive memory allocation while the JVM reads the payload, potentially leading to denial of service. The issue affects only deployments where RMI instrumentation is enabled and an RMI endpoint is network-reachable. This issue has been fixed in version 2.27.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://github.com/open-telemetry/opentelemetry-java-instrumentation/security/advisories/GHSA-fq3f-m5qm-99f5"],"products":["linuxfoundation:opentelemetry_instrumentation_for_java"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-54712","score":0.0046,"percentile":0.39602,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-fq3f-m5qm-99f5","url":"https://osv.dev/vulnerability/GHSA-fq3f-m5qm-99f5","summary":"OpenTelemetry Javaagent RMI context propagation allows resource exhaustion","modified":"2026-07-29T17:30:32.324974816Z","packages":[{"ecosystem":"Maven","name":"io.opentelemetry.javaagent:opentelemetry-javaagent","purl":"pkg:maven/io.opentelemetry.javaagent/opentelemetry-javaagent","ranges":["<2.27.0"],"fixed":["2.27.0"]}]}],"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).
