AWS Marketplace subsidiary account authorization

๐Ÿ”” Today AWS enables partners with multiple legal entities to publish a single product listing in a primary account and authorize local subsidiaries to sell it through direct private offers. The primary account retains listing ownership and controls which subsidiaries can sell specific products and to which buyer countries. Each subsidiary transacts under its own tax identity, chooses supported currencies, and configures disbursement preferences and bank accounts. A consolidated AWS Marketplace insights report in the primary account shows offers, agreements, and renewals across connected subsidiaries, and authorizations or connections can be revoked at any time.

Cisco firewall zero-day under active exploitation

๐Ÿ”’ A high-severity logic flaw in the Remote Access SSL VPN of Cisco Secure Firewall ASA and FTD (CVE-2026-76418, 8.6) is being actively exploited to crash devices. The issue triggers when secondary authentication is configured on a tunnel group and can allow an unauthenticated attacker to send a crafted request that reloads the device, causing denial of service. Cisco says there are no workarounds but has released patches and recommends immediate updates; a temporary mitigation is to disable secondary authentication on affected tunnel groups.

RDS autoscaling expands to additional volumes

๐Ÿ”” Amazon RDS for SQL Server and Amazon RDS for Oracle now support RDS storage autoscaling on additional storage volumes, enabling automatic, zero-downtime scaling as database workloads grow. You can add up to three additional volumes per instance to increase capacity up to 256 TiB and set a desired maximum for each volume while autoscaling manages growth. Autoscaling continuously monitors actual consumption, scales up when utilization nears provisioned capacity, and applies to new and existing instances at no extra charge; you pay only for provisioned storage. The feature is available in all commercial AWS Regions and AWS GovCloud (US), and can be enabled via the Console, CLI, or API.

Google Cloud adds $250K Root-in-Cloud VRP tier

๐Ÿ”’ The Google Cloud Vulnerability Reward Program (VRP) has introduced a new $250,000 "Root-in-Cloud" top-tier bounty to reward high-impact architectural research such as tenant-isolation bypasses and cross-service logic flaws. This tier requires demonstrable full administrative control over arbitrary organizations or projects without prior access and uses deterministic proof-of-root criteria to validate findings safely. Researchers are required to stop probing production Borg infrastructure upon any execution, and the VRP panel will evaluate entry points and impact to determine eligibility. The change responds to rising automated report volumes and aims to incentivize deep, human-led research alongside agentic tools.
