Summary
Details

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.
