Description

Summary

When the Slack integration is enabled, Slack channel metadata (topic/description) could be incorporated into the model's system prompt.

Impact

Prompt injection is a documented risk for LLM-driven systems. This issue increased the injection surface by allowing untrusted Slack channel metadata to be treated as higher-trust system input.

This is relevant only for deployments that enable Slack. In deployments where tool execution is enabled, a successful injection could lead to unintended tool invocations and/or unintended data exposure.

Affected Packages / Versions

  • npm: openclaw < 2026.2.3

Patched Versions

  • npm: openclaw >= 2026.2.3

Mitigation

  • If you do not use Slack: no action required.
  • If you use Slack: upgrade to a patched version.

Fix Commit(s)

Thanks @KonstantinMirin for reporting.
