CVE-2026-57122
High
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.
