The `host.id` resource attribute detector launches the `sh` and `ioreg` executables by bare name rather than by absolute path, so both are resolved\nthrough the `PATH` environment variable.\n\nA 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\ncode execution/privilege escalation.\n\n### Details\n\nThe implementation of the host detector macOS has always invoked `ioreg` and `sh` via their bare names since it was implemented by open-telemetry/opentelemetry-dotnet-contrib#1631.\n\nThe vulnerability was fixed by open-telemetry/opentelemetry-dotnet-contrib#4760 which executes `ioreg` directly using its absolute path.\n\n### Impact\n\nApplications running on **macOS** that use the `OpenTelemetry.Resources.Host`","public_affected_ranges":["< 1.16.0-beta.2"]}],"null_published_at":"2026-11-04T10:04:27.944Z","source_updated_at":"2026-09-16T13:54:17.000Z","source_disclosed_at":"2026-09-16T13:54:16.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-01T19:09:30.244Z"}],"next_cursor":null,"snapshot_revision":"42594"}
