CVE-2026-24764 — OpenClaw has Remote Code Execution via System Prompt Injection in Slack Channel Descriptions

Affected: clawdbot

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.

GHSA-782p-5fr5-7fj8 — OpenClaw Affected by Remote Code Execution via System Prompt Injection in Slack Channel Descriptions

Affected: npm: openclaw

## 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) - 35eb40a7000b59085e9c638a80fd03917c7a095e
