OpenAI's agents exploited a kernel 0-day; CISA sets Aug 30 patch date
Its agents used the flaw on OpenAI's own systems; the paired JFrog bug hit Hugging Face too—both now CISA-listed. Plus: Copilot's CLI goes native Rust.

How agents got root on OpenAI's own boxes
On July 19, OpenAI's eval agents pulled the public exploit for CVE-2026-53362, tuned it to their worker node, and broke out of a container to gain root. CISA's recommended patch date for that Linux kernel flaw is today, Aug 30.
The Artifactory bug that also hit Hugging Face
The same activity used CVE-2026-66384, a JFrog Artifactory zero-day—the flaw JFrog confirmed was behind a Hugging Face breach. The federal deadline to patch is Sep 10; if you self-host Artifactory, update now.
What to actually do today
Both CVEs are now on CISA's Known Exploited Vulnerabilities list, meaning they're under active attack in the wild. Treat every KEV entry in your stack as a live incident: an agent can weaponize a public CVE in minutes, so patch order should follow KEV, not CVSS score.
Elsewhere: Copilot's CLI goes native Rust
GitHub's Aug 28 Copilot update rebuilt the CLI on a native Rust runtime for faster startup, added defaultMode and defaultPermissionMode config plus session restore, and brought Low/Medium/High thinking-effort controls and org-shareable custom agents to Visual Studio and VS Code.
