How to fix it
Joomla Content Editor is affected by an access control flaw that can allow unauthenticated profile creation and PHP upload or execution. Apply the JCE security update or vendor patch, then inspect the Joomla site for uploaded webshells and unauthorized editor profiles. This should be treated as a possible full-site compromise if the component was publicly reachable.
- Inventory Joomla sites using Joomla Content Editor and record the installed JCE version.
- Upgrade JCE to the fixed release or apply the vendor patch for older supported sites.
- Disable public access to JCE profile management and remove any unauthorized editor profiles.
- Block PHP execution in upload, images, media, cache, tmp, and user-controlled directories where possible.
- Inspect uploaded files, templates, plugins, administrator users, and configuration.php for unauthorized changes.
- Rotate Joomla administrator credentials, database credentials, FTP credentials, and API tokens if suspicious uploads are found.
- Clear Joomla cache, CDN cache, and server opcache after removing malicious files and deploying the fix.
