CVE-2026-0281Network attack vector

Session-token disclosure via sensitive cache exposure

Published Jul 9, 2026 · Updated Jul 9, 2026

Information disclosure in the PAN-OS management web interface allows remote attackers to obtain web session tokens after a user clicks a link. Palo Alto Networks identifies sensitive session-token caching as the weakness but does not disclose the affected cache or request path. Exploitation requires network access to the management interface and active interaction by a legitimate user, exposing that user's session to token-based access.
