OpenTelemetry Go SDK Vulnerable to Arbitrary Code Execution via PATH Hijacking

CVE-2026-24051 / GHSA-9h8m-3fm2-qjrq

More information

Details

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.

opentelemetry-go: BSD kenv command not using absolute path enables PATH hijacking

CVE-2026-39883 / GHSA-hfvc-g4fc-pqhx

More information

Details

Summary

The fix for GHSA-9h8m-3fm2-qjrq (CVE-2026-24051) changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms.

Root Cause

sdk/resource/host_id.go line 42:

if result, err := r.execCommand("kenv", "-q", "smbios.system.uuid"); err == nil {

Compare with the fixed Darwin path at line 58:

result, err := r.execCommand("/usr/sbin/ioreg", "-rd1", "-c", "IOPlatformExpertDevice")

The execCommand helper at sdk/resource/host_id_exec.go uses exec.Command(name, arg...) which searches $PATH when the command name contains no path separator.

Affected platforms (per build tag in host_id_bsd.go:4): DragonFly BSD, FreeBSD, NetBSD, OpenBSD, Solaris.

The kenv path is reached when /etc/hostid does not exist (line 38-40), which is common on FreeBSD systems.

Attack
  1. Attacker has local access to a system running a Go application that imports go.opentelemetry.io/otel/sdk
  2. Attacker places a malicious kenv binary earlier in $PATH
  3. Application initializes OpenTelemetry resource detection at startup
  4. hostIDReaderBSD.read() calls exec.Command("kenv", ...) which resolves to the malicious binary
  5. Arbitrary code executes in the context of the application

Same attack vector and impact as CVE-2026-24051.

Suggested Fix

Use the absolute path:

if result, err := r.execCommand("/bin/kenv", "-q", "smbios.system.uuid"); err == nil {

On FreeBSD, kenv is located at /bin/kenv.

Severity

  • CVSS Score: 7.3 / 10 (High)

  • Add WithCardinalityLimitSelector for metric reader for configuring cardinality limits specific to the instrument kind. (#​7855)

Changed

  • Introduce the EMPTY Type in go.opentelemetry.io/otel/attribute to reflect that an empty value is now a valid value, with INVALID remaining as a deprecated alias of EMPTY. (#​8038)
  • Refactor slice handling in go.opentelemetry.io/otel/attribute to optimize short slice values with fixed-size fast paths. (#​8039)
