cloud storage

A cross-tenant data exposure flaw in Cloudflare's Containers and Sandboxes has been disclosed and fixed. The issue stemmed from dm-thin storage pools running with skip_block_zeroing enabled, meaning newly written 4 KiB pages into unmapped 64 KiB blocks could leave residual data on raw devices. A Workers Paid tenant could reportedly read up to 60 KiB of data left behind by a previous tenant from /dev/vdc. Cloudflare has patched the issue, and security communities are discussing the implications of shared-storage isolation failures in multi-tenant cloud platforms.

Backblaze has released its drive statistics report for the second quarter of 2026, continuing its long-running series detailing failure rates across the hard drives in its cloud storage fleet. The reports are closely watched in the tech community as a rare public source of real-world reliability data for consumer and enterprise drives, often sparking debate over which manufacturers and models perform best.

A question on Hacker News is asking whether AI agents should be granted access to cloud storage under least-privilege permissions. The discussion touches on how developers can let automated agents read and write files without exposing broader credentials or sensitive data. Commenters are weighing the security trade-offs of agent-driven workflows against current identity and access management tools.

A technology writer describes handing a nearly full SSD to a locally running large language model and asking it to identify files that could be safely deleted. The piece highlights a practical, privacy-friendly use of local AI: instead of sending data to the cloud, the model analyses the drive on the user's own machine and suggests what can be removed to free up storage space.
