Kurz gesagt
- CVE-2026-41310 ist eine Schwachstelle (MITTEL (CVSS 5.3)) in OpenTelemetry.Exporter.Zipkin, opentelemetry.exporter.zipkin (opentelemetry).
- Wahrscheinlichkeit einer Ausnutzung in den nächsten 30 Tagen (EPSS): 0.31%, höher als bei 24.0% aller Schwachstellen.
- Abhilfe: auf 1.15.3 oder neuer aktualisieren.
Description
Summary
The Zipkin exporter remote endpoint cache accepted unbounded key growth derived from span attributes. In high-cardinality scenarios, this could increase process memory usage over time and degrade availability.
Details
- Introduce a bounded, thread-safe LRU cache for remote endpoints.
- Enforce fixed maximum size to prevent unbounded growth.
Impact
- A process using Zipkin export for client/producer spans could experience avoidable memory growth under sustained unique remote endpoint values.

NVD description
OpenTelemetry.Exporter.Zipkin is the .NET Zipkin exporter for OpenTelemetry. In versions 1.15.2 and earlier, the Zipkin exporter remote endpoint cache accepts unbounded key growth derived from span attributes. In high-cardinality scenarios, a process using Zipkin export for client or producer spans could experience avoidable memory growth under sustained unique remote endpoint values, increasing process memory usage over time and degrading availability. This issue is fixed in version 1.15.3, which introduces a bounded, thread-safe LRU cache for remote endpoints with a fixed maximum size.
