Check wordpress-version

Overview

Checks the installed WordPress version against the endoflife.date API and alerts if the version is end-of-life or if newer releases are available. The check must run on the WordPress server itself, as it reads the version from the WordPress installation directory (wp-includes/version.php).

Data Collection:

  • Reads the WordPress version from <path>/wp-includes/version.php using a regex match on $wp_version

  • Queries the endoflife.date API to fetch EOL dates and latest available versions

  • Caches API responses in a SQLite database to reduce network calls
