Summary
OpenClaw Discord moderation authorization used untrusted sender identity in tool-driven flows
Details

Overview

Discord moderation action handling (timeout, kick, ban) used sender identity from request parameters in tool-driven flows, instead of trusted runtime sender context.

Impact

In setups where Discord moderation actions are enabled and the bot has the necessary guild permissions, a non-admin user could request moderation actions by spoofing sender identity fields.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published affected version (as of 2026-02-19): 2026.2.17
  • Affected range: <=2026.2.17
  • Fixed in planned next release: 2026.2.18

Fix

  • Moderation authorization now uses trusted sender context (requesterSenderId) instead of untrusted action params.
  • Added permission checks for required guild capabilities per action.

Fix Commit(s)

  • 775816035ecc6bb243843f8000c9a58ff609e32d
