WooCommerce running on unmaintained plugins
The average Australian WooCommerce store that has been live for five or more years has between 20 and 35 plugins installed. Of those, several are typically unmaintained: the developer has abandoned the plugin, the last update was over two years ago, or the plugin has known security vulnerabilities documented in the WordPress vulnerability database that have not been patched. Unmaintained plugins create two categories of risk. The first is security: a plugin with a known exploitable vulnerability is an active attack surface, and WooCommerce stores are targeted because they hold customer payment data and personal information. The second is PHP compatibility: when your hosting provider upgrades the PHP version on your server — which they do periodically, and often with limited notice — plugins built for older PHP versions can fail silently or generate fatal errors that take part of your store offline. An audit of your plugin stack, cross-referenced against the WordPress vulnerability database and PHP compatibility data, typically identifies three to six plugins that need immediate replacement or removal in a store that has been running for five-plus years without regular maintenance.
