medium Tenable Cloud Security Plugin ID 440794

Description

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

 - OpenTelemetry dotnet is a dotnet telemetry framework. From 1.13.1 to before 1.15.2, When exporting
 telemetry to a back-end/collector over gRPC or HTTP using OpenTelemetry Protocol format (OTLP), if the
 request results in a unsuccessful request (i.e. HTTP 4xx or 5xx), the response is read into memory with no
 upper-bound on the number of bytes consumed. This could cause memory exhaustion in the consuming
 application if the configured back-end/collector endpoint is attacker-controlled (or a network attacker
 can MitM the connection) and an extremely large body is returned by the response. This vulnerability is
 fixed in 1.15.2. (CVE-2026-40182)

Solution

Update the OpenTelemetry.Exporter.OpenTelemetryProtocol library and its related packages to version 1.15.2 or later.
