CVE-2026-24764

OpenClaw has Remote Code Execution via System Prompt Injection in Slack Channel Descriptions

3.7 LowFix available

OpenClaw (formerly Clawdbot) is a personal AI assistant users run on their own devices. In versions 2026.2.2 and below, when the Slack integration is enabled, channel metadata (topic/description) can be incorporated into the model's system prompt. Prompt injection is a documented risk for LLM-driven systems. This issue increases the injection surface by allowing untrusted Slack channel metadata to be treated as higher-trust system input. This issue has been fixed in version 2026.2.3.

OpenClaw Affected by Remote Code Execution via System Prompt Injection in Slack Channel Descriptions

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.
