Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
PraisonAI 是一个多智能体团队系统。在 4.6.59 版本之前，WhatsApp 和 Linear 机器人的 Webhook 处理器仅在配置了 或 时才验证 HMAC 签名；若未配置，则直接解析并分发未签名的请求体。能够访问 Webhook 路由的远程未认证客户端可以伪造消息、评论或智能体会话事件，冒充平台用户，影响智能体的提示词（prompt）和行为，并干扰机器人处理流程。该问题已在 4.6.59 版本中修复。

Vulnerability Title
PraisonAI: Webhook signature verification skipped (fail-open) when secret unset, allowing forged inbound webhooks (WhatsApp & Linear bots)
Source: CVE Program / CVE List V5
Vulnerability 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.
