Legacy Bug Exposes Cloud Backbone

A 13‑year‑old use‑after‑free in Redis can be exploited via default‑enabled Lua scripting to escape the sandbox and gain remote code execution. With Redis used across ~75% of cloud environments and at least 60,000 Internet‑exposed instances lacking authentication, one flaw can become a mass‑compromise vector without rapid patching and safer defaults. — It shows how default‑on extensibility and legacy code in core infrastructure create systemic cyber risks that policy and platform design must address, not just patch cycles.
