CRITICAL 9.1DOWNGRADE

CVE-2025-69690 is a critical-severity flaw (CVSS 9.1) affecting pfsense. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Netgate pfSense CE 2.7.2 allows code execution by using the module installer with a backup file with a serialized PHP object containing the post_reboot_commands property. NOTE: the Supplier disputes this because this installer is only available to admins and they are intentionally allowed to execute PHP code.

Affected: 2.7.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.7.2

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
