CVE-2026-39883 Details
Description
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.
A PATH hijacking vulnerability has been identified in OpenTelemetry-Go, affecting versions 1.15.0 prior to 1.42.0. The issue arises in the resource detection process on BSD and Solaris platforms, where the 'kenv' command is executed without an absolute path. This oversight allows an attacker with local access to the system to place a malicious 'kenv' binary earlier in the PATH, which can then be executed by the application, leading to arbitrary code execution.
Users can upgrade to OpenTelemetry-Go version 1.43.0 or later, where this vulnerability has been fixed.
