CVE-2026-24051 — OpenTelemetry-Go Affected by Arbitrary Code Execution via PATH Hijacking

Affected: open-telemetry opentelemetry-go

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.

GHSA-8rm2-7qqf-34qm — Prometheus: Remote read endpoint allows denial of service via crafted snappy payload

Affected: Go: github.com/prometheus/prometheus

### Impact

The remote read endpoint (`/api/v1/read`) does not validate the declared decoded length in a snappy-compressed request body before allocating memory. An unauthenticated attacker can send a small payload that causes a huge heap allocation per request. Under concurrent load this can exhaust available memory and crash the Prometheus process.

### Patches _Has the problem been patched? What versions should users upgrade to?_

Fixed in 3.11.3 and 3.5.3 LTS. Users should upgrade to these versions or later.

### Workarounds User who can not upgrade can place Prometheus behind a reverse proxy or firewall that requires authentication before requests reach /api/v1/read.
