Palo Alto Networks has confirmed a critical buffer overflow vulnerability, designated as CVE-2026-0300, which has been actively exploited by malicious actors. This flaw affects the PAN-OS software and allows for remote code execution with root-level privileges through the public management portal. Because the vulnerability was utilized in real-world attacks before a patch was issued on May 13, 2026, many installations may already be compromised. Organizations are urged to check for signs of exploitation and apply the latest security updates immediately to secure their network infrastructure.
