Cloudflare Containers flaw exposed cross-tenant data fragments

Original: Discover how a Cloudflare Containers data flaw exposed cross-tenant fragments. Learn about the skip_block_zeroing thin p

A reported vulnerability in Cloudflare Containers may have allowed fragments of one customer's data to be visible to another tenant. The issue is linked to a thin provisioning weakness known as skip_block_zeroing, where storage blocks are not properly zeroed before reuse. Security commentators are discussing how such flaws arise in shared cloud infrastructure and what they mean for container isolation and multi-tenant data protection.
