What to do
- Update to the latest version (3.1.4). Anything older than 1.7.3 has at least one known issue listed below. Dashboard → Updates, or Plugins → “update now”.
- 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 wp-super-cache --field=version shows what you run; wp plugin update wp-super-cache updates it.

Details from the advisory
The parameters $cache_path, $wp_cache_debug_ip, $wp_super_cache_front_page_text, $cache_scheduled_time, $cached_direct_pages used in the settings of WP Super Cache WordPress plugin before 1.7.3 result in RCE because they allow input of '$' and '\n'. This is due to an incomplete fix of CVE-2021-24209.

- CVE record (the advisory publisher) · score by NVD
Details from the advisory
The WP Super Cache WordPress plugin before 1.7.2 was affected by an authenticated (admin+) RCE in the settings page due to input validation failure and weak $cache_path check in the WP Super Cache Settings -> Cache Location option. Direct access to the wp-cache-config.php file is not prohibited, so this vulnerability can be exploited for a web shell injection.
