NVD Description

Note: Versions mentioned in the description apply only to the upstream opentelemetry-collector-contrib package and not the opentelemetry-collector-contrib package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
