This vulnerability (CVE-2026-0281) involves the use of cache containing sensitive information (CWE-524) in Palo Alto Networks PAN-OS software. An attacker with network access to the management web interface can obtain web session tokens without authentication, but only after a legitimate user clicks a malicious link provided by the attacker. The issue affects PA-Series and VM-Series firewalls and Panorama (virtual and M-Series) but not Cloud NGFW or Prisma Access. The vulnerability requires user interaction and network access to the management interface. No official remediation or patch information is provided. The vendor recommends restricting management interface access to trusted internal IP addresses as a best practice to minimize risk.

An attacker can disclose sensitive web session tokens by exploiting this vulnerability, potentially allowing unauthorized access to management sessions. However, exploitation requires user interaction (clicking a malicious link) and network access to the management web interface. The overall severity is low (CVSS 2.1), indicating limited impact and exploitability.

No official patch or remediation level is currently provided. The vendor recommends restricting access to the management web interface to trusted internal IP addresses as a best practice to reduce exposure. Organizations should follow Palo Alto Networks' guidelines for securing management access. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
