The Joomla extension Helix Ultimate is vulnerable to an unauthenticated arbitrary file deletion.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-57830 represents a critical vulnerability in the Joomla Helix Ultimate extension that allows attackers to delete arbitrary files without authentication. With a CVSS score of 9.1, this vulnerability poses severe risk to organizations running vulnerable Joomla instances, as attackers can remove critical application files, configuration files, or backups to cause denial of service, data loss, or facilitate further compromise. The vulnerability stems from improper authorization controls (CWE-862), meaning the extension fails to properly verify user permissions before executing file deletion operations. Any organization using the Helix Ultimate extension is potentially affected, making this a broad-impact threat requiring immediate patching and detection efforts.

Casky's 283 matched security skills leverage Claude AI with extended reasoning to detect the attack patterns behind this vulnerability by correlating indicators across MITRE ATT&CK Privilege Escalation (TA0004) and Credential Access (TA0006) techniques. Practitioners using Casky would observe detection findings flagging unauthenticated requests to Helix Ultimate administrative endpoints, suspicious HTTP DELETE or POST requests targeting file paths without proper session validation, and patterns of file system operations executed under web server context without corresponding user authentication. The platform's skills would highlight the absence of authorization checks in request handling, enabling security teams to identify exploitation attempts before files are deleted and to recognize lateral movement patterns where attackers leverage file deletion to disable security monitoring or remove audit logs.
