AI-suggested

Upgrade PraisonAI to version 4.6.59 or later, where the webhook handlers enforce HMAC signature verification regardless of secret configuration. Until the upgrade, ensure that WHATSAPP_APP_SECRET and LINEAR_WEBHOOK_SECRET are properly configured to enable signature verification. Patch status is confirmed fixed in 4.6.59.

Description

PraisonAI is a multi-agent teams system. Prior to 4.6.59, the WhatsApp and Linear bot webhook handlers verify HMAC signatures only when WHATSAPP_APP_SECRET or LINEAR_WEBHOOK_SECRET is configured and otherwise parse and dispatch unsigned request bodies. A remote unauthenticated client that reaches the webhook route can forge messages, comments, or agent-session events, impersonate platform users, influence agent prompts and actions, and disrupt bot processing. This issue is fixed in 4.6.59.
