description

WordPress Core versions 4.7 through 7.1.3 are affected by an upgrade-time race condition involving web-accessible staging files. An unauthenticated attacker may execute code on the server if a full-package core upgrade is in progress.

mitigation

Do not perform full-package core upgrades while the site is publicly accessible; restrict access to the site for the duration of the upgrade. Monitor for and apply the vendor's corrective update when it becomes available.
