Title

OpenClaw资源管理错误漏洞（CNVD-2026-16893）

Description

OpenClaw是一款用于权限管理的命令行工具。 OpenClaw 2026.3.13之前版本存在安全漏洞，该漏洞源于在验证x-telegram-bot-api-secret-token请求头之前，软件会先行读取并缓冲Webhook请求体。攻击者可利用该漏洞通过向Webhook端点发送大量POST请求，在身份验证发生前耗尽服务器的内存、连接和JSON解析资源，从而发起拒绝服务攻击。

CVE-2026-32980 (GCVE-0-2026-32980)

Vulnerability from cvelistv5 – Published: 2026-03-29 12:44 – Updated: 2026-06-23 16:15

Title

OpenClaw < 2026.3.13 - Resource Exhaustion via Unauthenticated Telegram Webhook Request

Summary

OpenClaw before 2026.3.13 reads and buffers Telegram webhook request bodies before validating the x-telegram-bot-api-secret-token header, allowing unauthenticated attackers to exhaust server resources. Attackers can send POST requests to the webhook endpoint to force memory consumption, socket time, and JSON parsing work before authentication validation occurs.
