CVE-2026-49393: OpenHuman: Unauthenticated Socket.IO RPC bypass allows invoking protected OpenHuman core controllers without the Bearer token

Noroxi assessment

Priority: Monitor (action score 33/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.29% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: tinyhumansai openhuman 0.56.0.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to tinyhumansai openhuman 0.56.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before 0.56.0, the core server protects HTTP POST requests to /rpc with bearer middleware but exposes Socket.IO rpc:request and chat:start handlers without equivalent transport or handler-level authentication. A local unauthenticated client can connect to the Socket.IO namespace and dispatch requests through the same protected controller path that rejects a missing bearer on /rpc. Depending on the selected method, the attacker can read configuration or health data, start agent flows, interact with integrated account APIs, alter local data, or stop and restart services. This issue is fixed in version 0.56.0.
