What is known
The WP Fastest Cache WordPress plugin before 0.9.5 is lacking a CSRF check in its wpfc_save_cdn_integration AJAX action, and does not sanitise and escape some the options available via the action, which could allow attackers to make logged in high privilege users call it and set a Cross-Site Scripting payload
Business impact
Successful exploitation of CVE-2021-24870, a medium vulnerability (CVSS 6.1) affecting wp fastest cache, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether wp fastest cache is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
