Prior to version…","details":"`OpenTelemetry.Resources.Host` NuGet package, which provides OpenTelemetry resource detectors for host, is affected by an untrusted search path vulnerability on macOS. Prior to version 1.16.0-beta.2, the `host.id` resource attribute detector launches the `sh` and `ioreg` executables by bare name rather than by absolute path, so both are resolved through the `PATH` environment variable. A local attacker who is less privileged than the host application, and who can influence `PATH` or write to a directory that appears in `PATH` ahead of the system directories, can have an arbitrary binary executed in the application's security context, resulting in local code execution/privilege escalation. This vulnerability only affect macOS hosts - Linux and Windows hosts are unaffected. Version 1.16.0-beta.2 contains a patch. No known workarounds are available.","published":"2026-09-08T21:18:43.447","modified":"2026-09-08T21:18:43.447","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/open-telemetry/opentelemetry-dotnet-contrib/pull/1631","label":"open-telemetry/opentelemetry-dotnet-contrib#1631"},"references":[{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-dotnet-contrib/pull/1631"},{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-dotnet-contrib/pull/4760"},{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-dotnet-contrib/security/advisories/GHSA-v8pv-4842-x354"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-08T21:18:43.447"}}
