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.
CVE-2021-24377 is a high severity with CVSS 8.1 Remote Code Execution issue affecting the Plugin Autoptimize. It affects Versions before 2.7.8 and is fixed in 2.7.8.
CVE-2021-24377 is tracked for the Plugin Autoptimize as high severity with CVSS 8.1. The affected range is Versions before 2.7.8. Update Autoptimize to 2.7.8 or newer where that version is compatible with the site.
