2DescriptionCVE.org
The Booking for Appointments and Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple Elementor widgets in versions up to and including 2.4.9. This is due to insufficient input sanitization and output escaping on the 'load_manually' parameter in the render() methods of classes. This makes it possible for authenticated attackers, with Contributor-level access and above who can use Elementor, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability was partially patched in version 2.4.8.
AnalysisAI
Stored Cross-Site Scripting in the Amelia Booking WordPress plugin (≤2.4.9) enables authenticated Contributor-level users with Elementor access to inject persistent JavaScript into booking-related pages via the unsanitized load_manually parameter across multiple Elementor widget render() methods. The injected payload executes in every subsequent visitor's browser session, producing cross-user, scope-changed impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions: (1) the target WordPress site must have both the Amelia Booking plugin at version 2.4.9 or earlier and the Elementor page-builder installed and active; (2) the attacker must hold at minimum a Contributor-level WordPress account with permission to create or edit pages in Elementor; and (3) the attacker-modified page must be published and subsequently visited by a victim. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.4 score (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) correctly reflects the scope-changed nature of stored XSS - the attacker operates at Contributor level, but impact cascades to all page visitors' browser sessions. … 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 | Update the Amelia Booking plugin to the version that incorporates WordPress changeset 3687762, which represents the more complete remediation beyond the partial fix shipped in 2.4.8. … Detailed patch versions, workarounds, and compensating controls in full report. |
