Summary
OpenClaw: Gateway `operator.write` can reach admin-only persisted `verboseLevel` via `chat.send` `/verbose`
Details

Summary

The chat.send path let authorized write-scoped callers persist /verbose session overrides even though the same stored session mutation is admin-only through sessions.patch.

Impact

A write-scoped gateway caller could persist verbose output for later runs and expose more reasoning or tool output than the operator intended.

Affected Component

src/auto-reply/reply/directive-handling.impl.ts, src/gateway/sessions-patch.ts

Fixed Versions

  • Affected: <= 2026.3.24
  • Patched: >= 2026.3.28
  • Latest stable 2026.3.28 contains the fix.

Fix

Fixed by commit c603123528 (fix(gateway): require admin for persisted verbose defaults).

Severity
5.4 (Medium)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
