CVE-2026-24051: Opentelemetry

High severity, CVSS 7.0. EPSS: 0.2% chance of exploitation in the next 30 days.

OpenTelemetry-Go is the Go implementation of OpenTelemetry. 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. A fix was released with v1.40.0.

Affected products

• Opentelemetry Opentelemetry: from 1.21.0, before 1.40.0 (fixed in 1.40.0)
