CVE-2021-24377: Autoptimize

High severity, CVSS 8.1. EPSS: 1.2% chance of exploitation in the next 30 days.

The Autoptimize WordPress plugin before 2.7.8 attempts to remove potential malicious files from the extracted archive uploaded via the 'Import Settings' feature, however this is not sufficient to protect against RCE as a race condition can be achieved in between the moment the file is extracted on the disk but not yet removed. It is a bypass of CVE-2020-24948.
