Terminal2Shell: 55-Year-Old ‘Zero-Day’ Dating Back to 1971 Claims to Affect Billions of Devices

What happened?

Terminal2Shell claims a critical flaw dating back to 1971 affects more than two billion devices, allowing anyone who opens a terminal to gain an interactive shell. However, the website is satire, not a confirmed vulnerability disclosure. Its “exploit” describes normal terminal use, making it a joke about security marketing rather than a newly discovered threat. The page calls the issue “TermGeddon,” lists its CVE as pending, and claims a CVSS score of 11.0 out of 10. That score is an immediate warning sign because the official CVSS scale stops at 10.0.
