## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-fcvx-5cxc-v5p8. This link is maintained to preserve external references.

## Original Description
OpenClaw before 2026.5.12 contains a notification bypass vulnerability allowing Slack reaction events to enter the agent pipeline despite disabled reaction notifications. Attackers can trigger unintended agent processing by sending reaction events when the feature is enabled, potentially leading to unauthorized processing of lower-trust input.

## Affected packages

- `openclaw <= 2026.5.7`

## Remediation

Refer to the advisory for the patched release.
