Is MemberHero safe to use?

Laskyr does not give safety verdicts. MemberHero is closed on wordpress.org. Closed on 2026-09-30. Closed plugins get no updates through WordPress, so new security holes will not be fixed for you. Keep MemberHero on the latest version and remove it if you do not use it.

Is MemberHero safe? Known vulnerabilities and latest version

Status: Closed 2026-09-30
Known issues on record: 6
Unpatched in latest: 0

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 wp-registration && wp plugin delete wp-registration
