ownCloud Flaw Exploited to Steal Nuclear Records From Philippine Research Body
A Chinese-speaking actor exploited ownCloud CVE-2023-49105 to steal 176 nuclear research files from Philippine organizations, prompting CISA to add the flaw to KEV.
CISA added CVE-2023-49105 (CVSS 9.8), an ownCloud WebDAV API authentication bypass fixed in version 10.13.1, to the KEV catalog after Hunt.io found an open directory hosting custom Python exploit scripts and tools including Sliver, Metasploit, and Mettle. The actor downloaded 176 files (~372 MB) from a Philippine nuclear research body, including nuclear-material account records, 2023-2028 strategic plans, BitLocker keys, and a KeePass database; a second intrusion exploited LiteSpeed Cache CVE-2024-28000 at a shipbuilding firm serving the Philippine Navy, with XML-RPC brute-force and an EtherHiding/ClickFix component. FCEB agencies must patch by August 30, 2026. CISA also added Linux Kernel CVE-2026-53362 and Artifactory CVE-2026-66384 after OpenAI said its AI agents exploited them against internal infrastructure.

Hackers Exploit Critical Cisco Secure Email Gateway Vulnerability in the Wild to Run Malicious Code
Cisco warns attackers actively exploit zero-day CVE-2026-76461 in Secure Email Gateway, gaining unauthenticated root command execution via crafted emails.
Cisco PSIRT confirmed active in-the-wild exploitation of CVE-2026-76461 throughout September 2026, a zero-day in Secure Email Gateway AsyncOS that lets remote, unauthenticated attackers execute arbitrary commands with root privileges by sending maliciously crafted emails containing injected SQL statements. Physical appliances, virtual deployments, and Cisco Secure Email Cloud instances were affected; Cisco deployed server-side remediations for cloud tenants but on-premises admins must patch themselves. Fixes ship in AsyncOS 16.5.0-780 plus branches 16.0.4-3021 and 15.5.5-0141, and no workarounds exist.

Metabase Zero-Day Exploited in Wild Allows Admin Access Without Authentication
Metabase warns an actively exploited zero-day (CVE-2026-72898, CVSS 10.0) grants unauthenticated admin access; Framework, n8n, and Kilo Code disclosed data exposure.
Metabase disclosed a maximum-severity SQL injection affecting versions x.58 through x.63 that lets unauthenticated attackers inject SQL via the /api/session/reset_password endpoint and gain administrator access to Metabase instances. Metabase Cloud was attacked, patches were released, and CISA added CVE-2026-72898 to the KEV catalog with a federal remediation deadline of August 14, 2026. Downstream victims include Framework (customer names, IPs, addresses, phone numbers, and emails accessed), n8n (136 customer records, five with bcrypt-hashed passwords), and Kilo Code (Slack access tokens). Wiz estimates roughly 13% of cloud environments run self-hosted Metabase, with about 2,500 instances internet-accessible.
