Known affected versions were inferred from fixed-version data and were not explicitly confirmed by the vendor: 8.1.19, 9.1.10, 10.1.1

The earliest recollection of this bug is traced back to PAN-OS 10.1.2 - July 22, 2025. This bug is fixed in PAN-OS versions 9.1.11, 8.1.20, 10.1.2. A fix was made to address a time-of-check to time-of-use (TOCTOU) race condition in the PAN-OS web interface that enabled an authenticated administrator with permission to upload plugins to execute arbitrary code with root user privileges ( CVE-2021-3054 ).
