Booking For Appointments And Events Calendar Amelia
Monthly
Unauthenticated privilege escalation in the WordPress plugin Booking for Appointments and Events Calendar - Amelia (Premium) versions 8.0 through 9.6.2 lets remote attackers gain full administrator control of a site. By abusing insufficient validation of the 'type' parameter in the customer update endpoint (with 'externalId' set to 0), an attacker elevates a customer to the manager role, then creates a provider entity linked to an existing administrator and overwrites that administrator's password. No public exploit has been identified at time of analysis, but the CVSS 9.8 rating and unauthenticated network reachability make this a high-priority patch for affected sites.
Stored XSS in the Amelia WordPress booking plugin (versions ≤ 2.2) allows unauthenticated attackers to persist malicious JavaScript that fires when a site administrator views the Calendar page. The attack chain exploits two compounding weaknesses: an explicit nonce-verification skip in AddBookingCommand (Command.php:186) that permits unauthenticated booking submissions, and unsafe interpolation of customer name fields into JavaScript template literals rendered via innerHTML in the FullCalendar eventContent callback (redesign/dist/index.js:199). No public exploit is confirmed at time of analysis, but the Wordfence disclosure provides sufficient technical detail for trivial weaponization.
Authenticated privilege escalation to Administrator in Amelia WordPress plugin (all versions ≤2.1.3) allows Provider-level users to hijack any account via Insecure Direct Object Reference. Attackers manipulate the externalId parameter during profile updates to map their session to arbitrary WordPress user IDs, including administrators, bypassing all authorization checks before password reset and user modification operations. EPSS data not provided; no confirmed active exploitation (CISA KEV) at time of analysis, though public exploit code exists via disclosed source code references.
The Amelia Booking plugin for WordPress contains an Insecure Direct Object Reference (IDOR) vulnerability in versions up to and including 9.1.2 that allows authenticated attackers with customer-level permissions to bypass authorization controls and modify user passwords, including administrator accounts, potentially leading to complete site takeover. This vulnerability affects the pro version of the plugin available on CodeCanyon and carries a CVSS score of 8.8 (HIGH). No evidence of active exploitation (KEV) or public proof-of-concept is currently documented, but the vulnerability has been publicly disclosed by Wordfence.
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. No public exploit has been identified at time of analysis, but the partial-then-full patch history across two separate changesets indicates the vendor required multiple iterations to close all affected widgets.
SQL Injection in the Amelia booking plugin for WordPress (versions through 2.4.3) allows authenticated attackers holding the wpamelia-manager role to exfiltrate arbitrary data from the site's database via the Customer Import feature. The flaw stems from unsanitized user-supplied parameters passed into pre-existing SQL queries without adequate escaping or prepared statement usage, enabling stacked or appended query manipulation. No public exploit code or active exploitation has been identified at the time of analysis, and the confidentiality-only impact (C:H/I:N/A:N) reflects read-level database access rather than modification or destruction capability.
Unauthenticated attackers can approve any WordPress booking in 'waiting' status via the admin-ajax endpoint in Amelia plugin versions up to 2.1.2, due to a logical short-circuit flaw that skips token validation when the booking status matches a specific condition. An attacker can craft a direct request to the publicly-accessible endpoint to approve arbitrary bookings without authentication. This impacts all installations with pending bookings and exposes the booking workflow integrity across WordPress sites using this plugin.
