The Joomla extension Helix Ultimate is vulnerable to an unauthenticated arbitrary file deletion.
AnalysisAI
Arbitrary file deletion in JoomShaper's Helix Ultimate template framework for Joomla allows unauthenticated remote attackers to delete files on the server due to a missing authorization check (CWE-862). Any anonymous user can reach the vulnerable functionality without credentials (PR:N/UI:N), enabling deletion of critical Joomla files to corrupt or take down the site. No public exploit has been identified at time of analysis, and the CVE is not listed in CISA KEV.
Technical ContextAI
Helix Ultimate is a widely-used template/framework extension for the Joomla CMS, providing layout, menu, and page-builder functionality for many Joomla themes. The affected package is identified by CPE cpe:2.3:a:joomshaper.com:helix_ultimate_extension_for_joomla covering all versions (wildcard). The root cause is CWE-862 (Missing Authorization): a file-deletion endpoint or task within the extension does not verify that the requester is authenticated or authorized, so a file-path parameter supplied by an anonymous request is acted upon directly. Because the flaw is exposed over the network via Joomla's standard request handling, it is reachable without any Joomla session or token.
RemediationAI
No vendor-released patch version is identified in the available data, so the specific fixed release must be confirmed directly with JoomShaper before upgrading; monitor the vendor page at https://www.joomshaper.com/joomla-templates/helixultimate and the Joomla Vulnerable Extensions List, then upgrade Helix Ultimate to the corrected version as soon as it is published. As compensating controls until a patch is applied: restrict access to the extension's file-handling task/endpoint at the web server or WAF layer (block the anonymous request path that triggers deletion), which may break legitimate front-end functionality that relies on that route; enforce strict filesystem permissions so the web server user cannot delete critical Joomla core or configuration files beyond what is operationally required; and take a full site and database backup so any deletion can be rapidly restored. If the extension is not essential, temporarily unpublishing or removing it eliminates exposure at the cost of losing its template features.
