CVE-2026-78075 · Severity: info · Published 2026-08-31

Helix Ultimate is a popular Joomla template that includes blog functionality for managing website content. A flaw in the image deletion feature allows article authors to delete arbitrary files from the server's `/images/` directory by manipulating file path parameters, even though they can only authenticate as authors. This could result in loss of important website assets and potential service disruption.

## Technical details

The vulnerability is a broken object-level authorization flaw in the `Blog::remove_image()` method. The function verifies that a user is authorized to edit a specific article ID, but fails to validate that the image path (src parameter) actually belongs to that article before deletion. On Joomla 3 sites with physical file deletion enabled, an authenticated author can supply any article ID they have edit access to, combined with an arbitrary file path under `/images/`, to delete files outside their intended scope. The attack requires valid author-level authentication and Joomla 3 with file deletion enabled.
