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."}], "lastModified": "2026-09-10T19:58:20.507", "sourceIdentifier": "security-advisories@github.com"}
