CVE-2026-54712 Details
Description
OpenTelemetry Java Instrumentation provides OpenTelemetry auto-instrumentation and instrumentation libraries for Java. 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.
A denial-of-service vulnerability has been identified in OpenTelemetry Java Instrumentation versions prior to 2.27.0. The issue arises in the RMI context propagation payload reader, which limits the number of context entries but not the total size of the strings read from the stream. This allows an attacker to send an oversized payload to an RMI endpoint on an instrumented JVM, causing excessive memory allocation while the JVM processes the payload. The vulnerability only affects deployments with RMI instrumentation enabled and where an RMI endpoint is accessible over the network.
Users can upgrade to OpenTelemetry Java Instrumentation version 2.27.0 or later to address this vulnerability.
