Palo Alto OS High vulnerability! May 13th patch to be released!

🚨 CRITICAL ALERT: Palo Alto Networks PAN-OS Vulnerability 🚨

A new critical vulnerability impacting Palo Alto Networks firewalls has been actively exploited in the wild.

CVE: CVE-2026-0300 ⚠️ Severity: 9.3 / Critical 🎯 Impact: Unauthenticated Remote Code Execution (RCE) with ROOT privileges 🌐 Affected: PAN-OS User-ID Authentication Portal exposed to the internet 🛠️ Patch Release Begins: May 13, 2026

Organizations using PA-Series or VM-Series firewalls should immediately:
• Restrict Authentication Portal access to trusted/internal IPs only
• Disable the Authentication Portal if not required
• Apply patches as soon as they become available
• Enable Threat Prevention signatures if supported

This vulnerability requires NO authentication and is already seeing limited active exploitation. If your firewall management or captive portal is internet-facing, prioritize mitigation immediately.

Cyber teams should be monitoring closely over the next 24-48 hours as patches begin rolling out across affected PAN-OS versions.
