HIGHPre-NVD 7.07.0—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.0 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 96% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
