Vulnerability AssessmentAI
| Exploitation | The target Joomla installation must have the Convert Forms extension installed and running a version prior to 5.2.5. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 6.9 reflects a network-reachable, no-authentication, low-complexity attack (AV:N/AC:L/AT:N/PR:N/UI:N), consistent with the vulnerability description. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies a Joomla site using Convert Forms by inspecting page source or HTTP response headers that reference the extension. Without any credentials, the attacker navigates directly to the front-end Submissions view URL and receives a listing of all form submissions, including submitted names, email addresses, and any other fields site visitors have completed. … |
| Remediation | Upgrade the Convert Forms extension to version 5.2.5 or later, which introduces proper server-side access control on the Submissions view. … Detailed patch versions, workarounds, and compensating controls in full report. |
