Is Build App Online safe to use?

Laskyr does not give safety verdicts. Build App Online is closed on wordpress.org. Closed on 2026-03-10 (reason given: Security Issue). Closed plugins get no updates through WordPress, so new security holes will not be fixed for you. Keep Build App Online on the latest version and remove it if you do not use it.

Which versions of Build App Online are vulnerable?

Known issues on record (newest first): Missing authorization check (1.0.23 and older); Cross-site request forgery (CSRF) (1.0.23 and older); File inclusion (1.0.23 and older); Weak password recovery (1.0.22 and older); Privilege escalation (1.0.19 and older); SQL injection (older than 1.0.19, fixed in 1.0.19). The full list with sources is on this page.

What should I do if my Build App Online is out of date?

Is Build App Online safe? Known vulnerabilities and latest version

Status: Closed 2026-03-10
Known issues on record: 9
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 build-app-online && wp plugin delete build-app-online

medium 5.3 CVE-2026-3651 · published 2026-03-21

Missing authorization check in Build App Online (1.0.23 and older)

Affected: 1.0.23 and older
Fixed in: unknown
Access needed (per CVSS): No login needed
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The Build App Online plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 1.0.23. This is due to the plugin registering the 'build-app-online-update-vendor-product' AJAX action via wp_ajax_nopriv_ without proper authentication checks, capability verification, or nonce validation in the update_vendor_product() function. The function accepts a user-supplied post ID from the request and calls wp_update_post() to modify the post_author field without validating whether the user has permission to modify the specified post. This makes it possible for unauthenticated attackers to modify the post_author of arbitrary posts to 0 (orphaning posts from their legitimate authors), or for authenticated attackers to claim ownership of any post by setting themselves as the author.
