Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The OpenTelemetry Go SDK (go.opentelemetry.io/otel/sdk) versions 1.21.0 up to 1.40.0 are affected on macOS/Darwin, though the advisory text cites v1.20.0 through 1.39.0. The resource detection code runs the ioreg system command using an untrusted search path. An attacker who can modify the PATH environment variable locally can execute arbitrary code in the context of the application. Upgrade to version 1.40.0 or later.
