Is Premium Addons for KingComposer safe? Known vulnerabilities and latest version

Status: Closed 2026-06-25
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 premium-addons-for-kingcomposer && wp plugin delete premium-addons-for-kingcomposer

medium 5.3 CVE-2026-12349 · published 2026-06-30

Missing authorization check in Premium Addons for KingComposer (1.1.1 and older)

Affected: 1.1.1 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 Premium Addons for KingComposer plugin for WordPress is vulnerable to unauthorized modification and loss of data in versions up to, and including, 1.1.1. This is due to missing authorization and capability checks on the add_custom_sidebar() and remove_custom_sidebar() AJAX handlers, both of which are exposed through wp_ajax_nopriv_* hooks and write directly to the octagon_custom_sidebar option via update_option(). This makes it possible for unauthenticated attackers to create arbitrary custom widget areas or delete existing custom sidebars, which can cause widgets assigned to those areas to silently lose their registration and stop rendering.
