Cloudflare fixes Containers cross-tenant flaw exposing customer data

Cloudflare patched a cross-tenant vulnerability in its Containers and Sandboxes service that permitted Workers Paid account customers to access residual data from other customers' containers on shared physical infrastructure. The flaw affected data isolation between tenants on the same host.

Why it matters: Cloudflare Containers and Sandboxes customers should verify they are running patched versions, as competitors' workloads on the same infrastructure may have been accessible before remediation.
