SCA: security update for OpenTelemetry.Exporter.Zipkin (GHSA-88hf-wf7h-7w4m)

medium Tenable Self-Hosted Container Security Plugin ID 440950

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-41310)

Solution

Update the OpenTelemetry.Exporter.Zipkin library and its related packages to version 1.15.3 or later.
