Telnetd Vulnerabilities

Multiple reports describe critical, actively exploited authentication‑bypass and remote‑code‑execution flaws in GNU InetUtils telnetd (notably CVE‑2026‑24061 and CVE‑2026‑32746) that enable unauthenticated root/RCE on hundreds of thousands of exposed Telnet servers, prompting urgent advisories to patch, disable Telnet, block port 23, and migrate to safer access methods.
