Description

Summary

Before OpenClaw 2026.4.2, the Gateway connect success snapshot exposed local configPath and stateDir metadata to non-admin clients. Low-privilege authenticated clients could learn host filesystem layout and deployment details that were not needed for their role.

Impact

A non-admin client could recover host-specific filesystem paths and related deployment metadata, aiding host fingerprinting and chained attacks. This was an information-disclosure issue, not a direct authorization bypass.

Fix Commit(s)
