Description

The Fastcache by Host.it plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.7.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to add or remove the plugin's page-cache rewrite rules in the site's root .htaccess file.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • hostspa Fastcache by Host.it — Up to and including 1.7.5
