Search: CVE-2026-0300

A buffer overflow vulnerability in the User-ID™ Authentication Portal (aka Captive Portal) service of Palo Alto Networks PAN-OS software allows an unauthenticated attacker to execute arbitrary code with root privileges on the PA-Series and VM-Series firewalls by sending specially crafted packets. The risk of this issue is greatly reduced if you secure access to the User-ID™ Authentication Portal per the best practice guidelines https://knowledgebase.paloaltonetworks.com/KCSArticleDetail by restricting access to only trusted internal IP addresses. Prisma Access, Cloud NGFW and Panorama appliances are not impacted by this vulnerability.

Researchers uncovered an AI-driven intrusion ecosystem operated by affiliates of INC and The Gentlemen ransomware groups via seven exposed command-and-control servers. The operators integrated commercial AI models, exploited edge devices at scale, and compromised thousands of targets, primarily in the US industrial manufacturing and healthcare sectors. The infrastructure included multiple custom encryptor builds and evidence of active victim encryption. Operational security failures exposed source code, credentials, AI session logs, and victim data. The campaign demonstrates advanced ransomware-as-a-service operations leveraging AI and custom tooling.
