"praisonai.bots.DiscordApproval" approves a pending dangerous tool call when it sees any later non-bot message in the configured Discord channel whose text is classified as approval, such as "yes". The decision is not bound to: - a Discord reply to the approval message; - a Discord thread created for that request; - a Discord interaction/button callback for that request; - an explicit approver user allowlist; or - an approval nonce visible only to intended approvers. As a result, any user who can post in the configured approval channel can approve a pending high-risk tool call by sending "yes" after the approval message appears. The same local PoV also shows that the Slack and Telegram messaging approval backends have no explicit approver allowlist parameter, but the primary report-grade issue is the Discord backend's unthreaded channel cross-talk: the approving message does not need to be a reply or otherwise request-bound.
