Apa masalahnya?

Balbooa Gridbox is a page builder for Joomla from the same vendor as Balbooa Forms. Versions up to and including 2.20.1 became known for several severe security flaws – seven of them carry their own CVE identifier.

Three reach the maximum score of 10 out of 10: a privilege escalation that allowed an administrator account to be created without a login (CVE-2026-65884), resetting anyone else’s password (CVE-2026-65887) and taking over existing accounts (CVE-2026-65888). On top of that come file access without a login, an SQL injection and a bypassable permission check.

This is the decisive point: with these flaws an update is not necessarily enough. If your site ran on a version up to 2.20.1 for any length of time, a planted administrator account may already exist. The update closes the way in – an account that is already there stays until it is removed.

Apakah situs Anda terdampak? – Begini cara memeriksanya

  1. Open the back end

    Sign in to the Joomla administrator.

  2. Check the version

    Open ExtensionsManageManage and filter for "Gridbox". If the version is 2.20.1 or lower, the site is vulnerable.

  3. Review the user list

    Open UsersManage and look for accounts you did not create yourself – especially ones with an odd user name and a throwaway address. Do not delete blindly; check first.

  4. Go through the extensions

    In ExtensionsManage also review the plugin list for entries you never installed.

Cara menutup celah keamanan ini

Sebelum setiap pembaruan: buat backup
Buat backup file dan database sebelum memperbarui – agar Anda dapat kembali ke kondisi semula jika terjadi masalah (misalnya dengan Akeeba Backup atau lewat penyedia hosting Anda).
  1. Before updating: back up

    Back up files and database before you update.

  2. Open the update centre

    Go to SystemUpdateExtensions and click Check for updates.

  3. Update Gridbox

    Select the entry and update to 2.20.2 or newer. 2.20.1 is not enough.

  4. Afterwards: check accounts

    Only after the update, go through the user list – an account created earlier does not disappear on its own.

Instalasi manual (alternatif)
If no update appears, download the package through your Balbooa account and install it via ExtensionsManageInstall.

Sumber unduhan resmi: via Balbooa (account required). Pastikan Anda menggunakan minimal versi Balbooa Gridbox 2.20.2 or newer.

Updating alone is not enough here
With these flaws an attacker could settle in permanently before you updated. Check the user list for unfamiliar administrators, the plugin list for unknown entries, then change all passwords and look through the file system for unexpected PHP files. Continued access attempts after the update are normal – automated scanners keep looking for vulnerable sites.
