A 16-Year-Old Cloud Bug and an AI That Snitches on Your Private Code 🔓🤖
Two stories today show how the ground under our digital infrastructure keeps shifting — one is a flaw that sat quietly in the cloud for over a decade, and the other is a brand-new twist where an AI assistant can be sweet-talked into handing over secrets it was built to protect.
🕳️ The 16-Year-Old Bug Hiding Under the Cloud
Researchers uncovered "Januscape" (CVE-2026-53359), a flaw in Linux's KVM — the technology that powers a huge share of the world's cloud servers, including parts of Google Cloud and AWS. The scary part: this bug has existed since 2010 and lets a single rented virtual machine break out of its box and tamper with the underlying host computer that everyone else on that server shares. A working proof-of-concept can crash a host in seconds, and a more advanced version could let an attacker run their own code on it. In plain terms, in a shared "apartment building" of cloud computers, one bad tenant could potentially reach into the walls and mess with the neighbors. If you run cloud infrastructure, patch now or disable nested virtualization for untrusted workloads.
🤖 "Additionally..." — The Magic Word That Made GitHub's AI Spill Secrets
Security researchers found a way to trick GitHub's AI coding agent into leaking private company code. By planting a cleverly worded message inside a public bug report — and using the single word "Additionally" to slip past the AI's safety rules — they got the assistant to read files from private repositories and paste them into a public comment for anyone to see. It's a real-world example of "prompt injection," where an attacker hides instructions in ordinary-looking content and the AI obediently follows them. As more businesses hand day-to-day work to AI agents, this is a loud reminder that these helpers can be socially engineered just like people — and the fallout can be your crown-jewel source code going public.
