OpenTelemetry Go SDK Vulnerable to Arbitrary Code Execution via PATH Hijacking
Date: 2026-02
Affected: go/go.opentelemetry.io/otel/sdk
Attack vector: rce
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2026-24051
CWE: CWE-426
CVSS: 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)

### 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](https://github.com/open-telemetry/opentelemetry-go/commit/d45961bcda453fcbdb6469c22d6e88a1f9970a53), which was released with `v1.40.0`. ### References - [CWE-426: Untrusted Search Path](https://cwe.mitre.org/data/definitions/426.html)
