Summary Plivo V3 signature verification canonicalized query ordering, but replay detection hashed the raw verification URL. Reordering query parameters preserved a valid signature while producing a fresh replay-cache key. Impact An attacker who captured one valid signed Plivo V3 webhook could...

OpenClaw 安全漏洞

OpenClaw is an intelligent artificial assistant open-sourced by OpenClaw. OpenClaw suffers from a security vulnerability that stems from the fact that rate limiting is only applied after successful Webhook authentication, which can be exploited by an attacker to bypass the rate limiting and...

CVE-2026-34505: Improper Restriction of Excessive Authentication Attempts
