openhuman: Cleartext Storage of Sensitive Information in an Environment Variable

Published Updated By the CyberSecBulletin desk

CVE-2026-54146 is a high-severity cleartext storage of sensitive information in an environment variable vulnerability in openhuman from Tinyhumansai, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected openhuman versions: >= 0.53.15, < 0.57.5. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.21% chance of exploitation within 30 days, which is low compared with other CVEs.

Official 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.

The underlying weakness: Cleartext Storage of Sensitive Information in an Environment Variable

The product uses an environment variable to store unencrypted sensitive information.

How developers prevent this class of flaw

  • If the environment variable is not necessary for the desired behavior, then remove it entirely, or clear it to an empty value.
