SCA: security update for OpenTelemetry.Resources.AWS, OpenTelemetry.Sampler.AWS (GHSA-28xm-prxc-5866)

medium Tenable Self-Hosted Container Security Plugin ID 440790

Description

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

 - The AWS X-Ray Remote Sampler package provides a sampler which can get sampling configurations from AWS
 X-Ray. Prior to 0.1.0-alpha.8, OpenTelemetry.Sampler.AWS reads unbounded HTTP response bodies from a
 configured AWS X-Ray remote sampling endpoint into memory. AWSXRaySamplerClient.DoRequestAsync called
 HttpClient.SendAsync followed by ReadAsStringAsync(), which materializes the entire HTTP response body
 into a single in-memory string with no size limit. The sampling endpoint is configurable via
 AWSXRayRemoteSamplerBuilder.SetEndpoint (default: http://localhost:2000). An attacker who controls the
 configured endpoint, or who can intercept traffic to it (MitM), can return an arbitrarily large response
 body. This causes unbounded heap allocation in the consuming process, leading to high transient memory
 pressure, garbage-collection stalls, or an OutOfMemoryException that terminates the process. This
 vulnerability is fixed in 0.1.0-alpha.8. (CVE-2026-41173)

Solution

Update the OpenTelemetry.Sampler.AWS library and its related packages to version 0.1.0-alpha.8 or later.
