GHSA-X4VP-4235-65HG OpenClaw has pre-auth webhook body parsing that can enable unauthenticated slow-request DoS

Impact OpenClaw webhook handlers for BlueBubbles and Google Chat accepted and parsed request bodies before authentication and signature checks on vulnerable releases. This allowed unauthenticated clients to hold parser work open with slow/oversized request bodies and degrade availability...

📄 GNU Inetutils telnetd NEW-ENVIRON Authentication Bypass

This Metasploit module exploits an authentication bypass vulnerability in GNU Inetutils telnetd. By sending a specially crafted NEW-ENVIRON subnegotiation with a USER variable containing -f root, an attacker can login as root without a password. This occurs because telnetd passes the environment...
