CVE-2026-56695Network attack vector

Cross-session disclosure via remotely invocable transcript commands

Published Jun 23, 2026 · Updated Jun 23, 2026

Information disclosure in OpenHarness 0.1.9 and earlier allows remote authenticated users to access other users' session snapshots. The ohmo gateway registers /resume and /summary with remote_invocable enabled and accepts arbitrary snapshot identifiers without enforcing session ownership. Access requires admission to a shared gateway channel and exposes stored prompts, credentials, tool output, and file paths.
