johnbillion/wp-crontrol
source listedECOSYSTEM: introduced 0; fixed 1.16.2
### Impact WP Crontrol includes a feature that allows administrative users to create events in the WP-Cron system that store and execute PHP code subject to the restrictive security permissions documented here. While there is _no known vulnerability in this feature on its own_, there exists potential for this feature to be vulnerable to RCE if it were specifically targeted via vulnerability chaining that exploited a separate SQLi (or similar) vulnerability. This is exploitable on a site if one of the below preconditions are met: * The site is vulnerable to a writeable SQLi vulnerability in any plugin, theme, or WordPress core * The site's database is compromised at the hosting level * The site is vulnerable to a method of updating arbitrary options in the `wp_options` table * The site is vulnerable to a method of triggering an arbitrary action, filter, or function with control of the parameters ### Patches As a hardening measure, WP Crontrol version 1.16.2 ships with a new feature that prevents tampering of the code stored in a PHP cron event. All PHP cron events are now secured via an integrity check that makes use of an HMAC

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
