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.
AnalysisAI
PraisonAI's WhatsApp and Linear bot webhook handlers fail open when their shared-secret environment variables are unset: HMAC signature verification is skipped entirely and the raw JSON body is parsed and dispatched as a trusted platform event. Any remote client that can reach the bot's webhook route (default /webhook) can forge WhatsApp messages or Linear AgentSession/Comment events without authentication, impersonating platform users and injecting attacker-controlled content into agent prompts and actions. …
