OpenTelemetry-Go has an incomplete fix for CVE-2026-24051: BSD kenv command not using absolute path enables PATH hijacking

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.15.0 to 1.42.0, the fix for 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. This vulnerability is fixed in 1.43.0.

## 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`.
