Unauthenticated network injection (PR:N) requiring victim page view (UI:R); XSS crosses into other users' browser context (S:C) with limited browser-scoped impact (C:L/I:L, A:N), not the vendor's C:H/I:H/A:H.

The iGMS Direct Booking WordPress plugin before 2.0 does not authorise or escape its widget appearance settings, allowing unauthenticated users to store arbitrary web scripts that execute in the context of an administrator viewing the iGMS Direct Booking WordPress plugin before 2.0 settings, and in the browser of any visitor to a page displaying the booking widget.
AnalysisAI
Unauthenticated stored cross-site scripting in the iGMS Direct Booking WordPress plugin (all versions before 2.0) lets any remote attacker write arbitrary JavaScript into the plugin's widget appearance settings, which is then rendered without escaping and executes in the browser of an administrator opening the settings page or of any visitor viewing a page that displays the booking widget. The write itself requires no credentials (CVSS vector PR:N) and no privileged configuration, so default installations are exposed; however, the payload only fires when a victim loads the affected page (UI:R), and the assessed impact is limited to low confidentiality and integrity with scope change (S:C/C:L/I:L/A:N) rather than the higher CIA values in the NVD base score. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No authentication required - the plugin fails to authorise writes to its widget appearance settings, so any unauthenticated user can store the payload against default installations of the iGMS Direct Booking plugin (all versions before 2.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Multiple signals converge on this being a genuine priority rather than a paper tiger. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: 2.0 - upgrade the iGMS Direct Booking plugin to version 2.0 or later, which is the only complete fix, since it closes both the missing authorization on the settings write and the missing output escaping; confirm the update through the WordPress plugin dashboard or by deploying the 2.0 package directly, and re-check any site that had prior exploitation for injected markup in the widget appearance options. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress installations for the iGMS Direct Booking plugin, identify any running versions earlier than 2.0, and treat every affected internet-facing site as compromised-adjacent - review recent administrator account activity, plugin/widget settings changes, and unexpected content or script insertions. …
