Is Fonts Manager safe to use?

Laskyr does not give safety verdicts. Fonts Manager is closed on wordpress.org. Closed on 2026-03-05 (reason given: Security Issue). Closed plugins get no updates through WordPress, so new security holes will not be fixed for you. Keep Fonts Manager on the latest version and remove it if you do not use it.

Is Fonts Manager safe? Known vulnerabilities and latest version

Status: Closed 2026-03-05
Known issues on record: 2
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 fonts-manager-custom-fonts && wp plugin delete fonts-manager-custom-fonts

Details from the advisory

The Fonts Manager | Custom Fonts plugin for WordPress is vulnerable to time-based SQL Injection via the ‘fmcfIdSelectedFnt’ parameter in all versions up to, and including, 1.2 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.
