Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.4.2

Description OpenClaw fails to filter Slack thread context by sender allowlist, which allows messages from non-allowlisted senders to enter the agent context. This enables attackers to inject unauthorized thread messages via replies from allowlisted users, bypassing sender access controls to manipulate the model context.
