# CVE-2026-54146: OpenHuman: Bearer token leak via process environment variable on macOS (same-UID local RCE primitive)

Affects OpenHuman 0.53.15 up to but not including 0.57.5 on macOS (Intel and Apple Silicon); other processes running as the same user can read the bearer token. Fixed in 0.57.5.

- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
- Known exploited (CISA KEV): no

CVE-2026-54146 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.8 (high) and affects openhuman; fixed in 0.57.5.

## Summary

OpenHuman's macOS desktop application exposes its per-launch core bearer token in a process environment variable, so a local attacker with low-privilege access can recover it and authenticate to the core JSON-RPC service. From there, the attacker can read agent memory and integrated-account data, invoke privileged actions, change configuration, and stop or disrupt services, all without root access.

## Affected

- tinyhumansai openhuman: from 0.53.15, fixed in 0.57.5

## Description

OpenHuman is an open-source agent harness available as a desktop application and Rust library. From 0.53.15 before 0.57.5 on macOS, core_process.rs in the Tauri desktop process publishes the per-launch OPENHUMAN_CORE_TOKEN bearer credential in its process environment even though the core now runs as an in-process task. Another process running as the same user can read that environment through the macOS KERN_PROCARGS2 process-inspection interface, recover the token together with the local host and port, and authenticate to the core JSON-RPC service with the authority of the desktop frontend. The attacker can read agent memory and integrated-account data, invoke privileged actions, change configuration, and stop or disrupt services without root access, developer mode, or changes to System Integrity Protection. This issue affects Intel and Apple Silicon macOS systems. This issue is fixed in version 0.57.5.

## FAQ

### Is CVE-2026-54146 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.
