Is Smart SEO Tool safe? Known vulnerabilities and latest version

What to do
- Replace it. A closed plugin gets no updates through WordPress, so any hole found from now on stays open.
- Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deleting removes its files; deactivating alone leaves them on the server.
- If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan, or have us clean it: Emergency Cleanup, $499.
With WP-CLI, once you have a replacement: wp plugin deactivate smart-seo-tool && wp plugin delete smart-seo-tool
