Upgrade go.opentelemetry.io/otel/sdk/resource to version 1.43.0 or higher.
Overview
Affected versions of this package are vulnerable to Untrusted Search Path through the hostIDReaderBSD.read function in sdk/resource/host_id.go. An attacker can execute a malicious kenv binary by placing it earlier in $PATH and triggering host ID detection on BSD or Solaris systems when /etc/hostid is absent. When an application initializes OpenTelemetry resource detection under those conditions, it runs the attacker-controlled command in the application's context, allowing local code execution and compromising the process running the Go application.
