The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered all federal civilian agencies to urgently remediate a critical authentication bypass vulnerability in Palo Alto Networks’ PAN-OS GlobalProtect VPN, tracked as CVE-2026-0257. The flaw, disclosed by Palo Alto Networks in a May 13, 2026 advisory with a CVSS score of 7.8, allows attackers to establish unauthorized VPN connections and access internal networks. CISA added the issue to its Known Exploited Vulnerabilities catalog and set a deadline of June 1, 2026 for federal agencies to patch or mitigate the flaw amid confirmed active exploitation, also urging private sector users to update systems promptly.
