パッケージ	影響を受けるバージョン	修正済みバージョン
go.opentelemetry.io/otel/sdk Go	`≥ 1.21.0, < 1.40.0`	`1.40.0`
opentelemetry opentelemetry	`≥ 1.21.0, < 1.40.0`	`1.40.0`

概要

Impact

The OpenTelemetry Go SDK in version v1.20.0-1.39.0 is vulnerable to Path Hijacking (Untrusted Search Paths) on macOS/Darwin systems. The resource detection code in sdk/resource/host_id.go executes the ioreg system command using a search path. An attacker with the ability to locally modify the PATH environment variable can achieve Arbitrary Code Execution (ACE) within the context of the application.

Patches

This has been patched in d45961b, which was released with v1.40.0.
