CVE-2026-57830 is an unauthenticated arbitrary file deletion vulnerability in the Helix Ultimate extension for Joomla by JoomShaper. Affected versions are 1.0 through 2.2.6. The flaw allows a remote attacker, without authentication or user interaction, to cause deletion of files accessible to the vulnerable application. The available information identifies the issue as arbitrary file deletion but does not provide the specific vulnerable function, endpoint, or code path.

Repository contains a small Python exploit set for an unauthenticated Joomla/JoomShaper Helix Ultimate vulnerability: one destructive PoC (helix_ultimate_delete_poc.py) and one non-destructive detector (helix_ultimate_detect.py), plus a detailed README documenting root cause, impact, and limitations. The exploit targets the Helix Ultimate system plugin's frontend com_ajax dispatch, specifically action=view-media for folder/image listing and action=delete-media for arbitrary file deletion or recursive folder deletion. Both scripts first fetch the target homepage and extract an anonymous CSRF token from HTML using regex, then POST to /index.php with option=com_ajax, helix=ultimate, request=task, and the chosen action. The delete PoC supports attacker-controlled paths and type=file/folder, including traversal examples using a single '/../' to escape one level above JPATH_ROOT and reach sibling directories on shared hosting. The detector safely proves exposure by listing /images only. The repository explicitly states this is a DoS and filesystem access issue, not RCE, and documents that an attempted installer-reexposure chain via deleting configuration.php was tested and disproved. Overall, this is a real, operational web exploit for unauthenticated read/list and delete capabilities against Helix Ultimate installations, with especially severe impact on shared-hosting environments.
