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.\n\n### Patches\nThis has been patched in [d45961b](https://github.com/open-telemetry/opentelemetry-go/commit/d45961bcda453fcbdb6469c22d6e88a1f9970a53), which was released with `v1.40.0`.\n\n### References\n- [CWE-426: Untrusted Search Path](https://cwe.mitre.org/data/definitions/426.html)","affected":[{"package":{"name":"go.opentelemetry.io/otel/sdk","ecosystem":"Go","purl":"pkg:golang/go.opentelemetry.io/otel/sdk"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.21.0"},{"fixed":"1.40.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-9h8m-3fm2-qjrq/GHSA-9h8m-3fm2-qjrq.json"}}],"references":[{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-9h8m-3fm2-qjrq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24051"},{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-go/commit/d45961bcda453fcbdb6469c22d6e88a1f9970a53"},{"type":"PACKAGE","url":"https://github.com/open-telemetry/opentelemetry-go"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2026-4394"}],"database_specific":{"cwe_ids":["CWE-426"],"github_reviewed":true,"github_reviewed_at":"2026-02-02T20:07:46Z","nvd_published_at":"2026-02-02T23:16:07Z","severity":"HIGH"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
