What to do

- If you cannot update right away, deactivate it until you can.
- Turn on auto-updates for it: Plugins → “Enable auto-updates” on its row.
- If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan.
With WP-CLI: wp plugin get wc-ajax-product-filter --field=version shows what you run; wp plugin update wc-ajax-product-filter updates it.

Details from the advisory
WCAPF – WooCommerce Ajax Product Filter plugin is vulnerable to time-based SQL Injection via the 'post-author' parameter in all versions up to, and including, 4.2.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
