Why am I seeing this Single-sourced — only Feedburner has this
Only Feedburner has this. It is here on that single source, so read it as one outlet's reporting until somebody else confirms it.
Single-sourced. No second organisation has confirmed it yet.

Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.
What happened
Malicious code running inside a Docker Sandboxes virtual machine on macOS could escape the project directory shared into it and read or change files anywhere else on the host, Docker warns in a security announcement on September 15. The escape runs with the rights of the host account that runs the virtual machine. The flaw, CVE-2026-77179, is rated Critical, affects versions
