## 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 Thanks @KonstantinMirin for reporting.
