Vulnerability AssessmentAI

Exploitation No authentication is required - the Fabrik order plugin accepts row reorder requests from any unauthenticated HTTP client (CVSS PR:N, AV:N, AC:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N, score 6.9) confirms low-complexity, unauthenticated, network-reachable exploitation with no preconditions - a broad attack surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker identifies a Joomla site running Fabrik 4.7.1 or earlier and sends a crafted HTTP request to the order plugin endpoint specifying a new row sequence. Because no access check is performed, the server accepts the request and persists the reordered record positions to the database. …
Remediation Upgrade the Fabrik extension to version 4.7.2 or later, which introduces proper access control enforcement in the order plugin. … Detailed patch versions, workarounds, and compensating controls in full report.
