SCA: security update for github.com/open-telemetry/opentelemetry-collector-contrib/receiver/githubreceiver (GHSA-w5cv-pw74-4rxc)

medium Tenable Cloud Security Plugin ID 443465

Description

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

 - The OpenTelemetry Collector Contrib repository contains components for the OpenTelemetry Collector. Prior
 to 0.151.0, the githubreceiver validates the receiver/githubreceiver/config.go RequiredHeaders
 configuration at startup, but receiver/githubreceiver/trace_receiver.go handleReq() does not check those
 headers on incoming webhook requests. An unauthenticated sender can therefore bypass an operator's
 required_headers authentication control and submit arbitrary webhook payloads. When the Secret field is
 empty, github.ValidatePayload also skips HMAC validation, leaving the webhook endpoint without either
 configured authentication mechanism. Successful exploitation can inject fabricated CI/CD trace data into
 the observability pipeline. This issue is fixed in version 0.151.0. (CVE-2026-55701)

Solution

Update the github.com/open-telemetry/opentelemetry-collector-contrib/receiver/githubreceiver library and its related packages to version 0.151.0 or later.
