SCA: security update for OpenTelemetry.Resources.Azure (GHSA-vc24-j8c5-2vw4)

medium Tenable Self-Hosted Container Security Plugin ID 441014

Description

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

 - OpenTelemetry.Resources.Azure is the .NET resource detector for Azure environments. In versions
 1.15.0-beta.1 and earlier, the AzureVmMetaDataRequestor class makes HTTP requests to the Azure VM instance
 metadata service and reads the response body into memory without any size limit. An attacker who controls
 the configured endpoint, or who can intercept traffic to it via a man-in-the-middle attack, 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. As a workaround, disable the Azure VM resource detector or use network-level controls such as
 firewall rules, mTLS, or a service mesh to prevent man-in-the-middle attacks on the Azure VM instance
 metadata endpoint. This issue is fixed in version 1.15.1-beta.1, which streams responses rather than
 buffering them entirely in memory and ignores responses larger than 4 MiB. (CVE-2026-41483)

Solution

Update the OpenTelemetry.Resources.Azure library and its related packages to version 1.15.1-beta.1 or later.
