Summary
A security flaw in Sipeed PicoClaw up to version 0.2.9 allows authentication bypass via capture-replay attack in the LINE Webhook component. The vulnerability affects the webhook.ParseRequest function in pkg/channels/line/line.go. Remote exploitation is possible, and a public exploit increases the risk.
Risk Assessment
The organization is at risk of unauthorized remote access, as an attacker can replay captured webhook requests, potentially leading to data integrity breaches or privilege escalation.
Recommendation
Immediately update Sipeed PicoClaw to a version newer than 0.2.9 if available, or implement temporary mitigations such as request uniqueness verification (e.g., nonce) and restricting access to the webhook endpoint.
