Affected: OpenClaw

OpenClaw versions prior to 2026.2.25 fail to enforce dmPolicy and allowFrom authorization checks on Discord direct-message reaction notifications, allowing non-allowlisted users to enqueue reaction-derived system events. Attackers can exploit this inconsistency by reacting to bot-authored DM messages to bypass DM authorization restrictions and trigger downstream automation or tool policies.

Affected: npm: openclaw

### Summary In OpenClaw `<= 2026.2.24`, Discord direct-message reaction notifications did not consistently apply the same DM authorization checks (`dmPolicy` / `allowFrom`) that are enforced for normal DM message ingress.

In restrictive DM setups, a non-allowlisted Discord user who can react to a bot-authored DM message could still enqueue a reaction-derived system event in the session.

This is a reaction-only ingress inconsistency. By itself it does not directly execute commands; practical impact depends on downstream automation/tool policy.

### Details The DM message path already enforces `dmPolicy`/`allowFrom` authorization, but the DM reaction-notification path previously allowed event enqueue under reaction mode checks without that same authorization gate.

Fix in `main` aligns reaction ingress with normal message preflight for Discord DM/group-DM/guild policy boundaries and applies equivalent DM reaction authorization hardening for Slack to keep channel behavior consistent.
