CVE-2026-54712: CWE-400: Uncontrolled Resource Consumption in open-telemetry opentelemetry-java-instrumentation
CVE-2026-54712 is a medium severity vulnerability in OpenTelemetry Java Instrumentation versions prior to 2.27.0. It involves uncontrolled resource consumption due to the RMI context propagation payload reader not limiting the aggregate size of strings read from the stream. An attacker able to reach an RMI endpoint on an instrumented JVM with RMI instrumentation enabled can send an oversized payload, causing excessive memory allocation and potential denial of service. This issue is fixed in version 2.27.0.
AI Analysis
Technical Summary
OpenTelemetry Java Instrumentation versions before 2.27.0 have a vulnerability (CWE-400) where the RMI context propagation payload reader limits the number of context entries but does not restrict the total size of strings read from the stream. This allows an attacker with network access to an RMI endpoint on an instrumented JVM to send an oversized payload, leading to excessive memory allocation and possible denial of service. The vulnerability affects only deployments with RMI instrumentation enabled and network-reachable RMI endpoints. The issue is resolved in version 2.27.0.
Potential Impact
An attacker who can access an RMI endpoint on a vulnerable JVM can cause excessive memory allocation by sending an oversized context propagation payload. This can lead to denial of service conditions due to resource exhaustion. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Upgrade to OpenTelemetry Java Instrumentation version 2.27.0 or later, where this vulnerability is fixed. If upgrading is not immediately possible, restrict network access to RMI endpoints on instrumented JVMs to prevent attacker exploitation. Patch status is confirmed fixed in version 2.27.0.
