Summary

OpenClaw versions before 2026.2.3 let Slack channel topic and description metadata enter the model's system prompt when the Slack integration is enabled. That treats untrusted channel text as higher-trust input, and in deployments with tool execution enabled, a successful injection could cause unintended tool invocations or data exposure.

Mitigation

Upgrade the npm package `openclaw` to version 2026.2.3 or later. If Slack is not used, no action is required.
