Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a Broken Access Control (Missing Authorization) vulnerability in the Themefic Hydra Booking WordPress plugin. The plugin fails to properly enforce authorization checks on certain functions or endpoints, allowing unauthenticated or under-privileged users to access functionality or data that should require higher privileges. The specific accessible functions are not detailed in the advisory.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Hydra Booking plugin is installedNavigate to WordPress admin dashboard > Plugins, or inspect the wp-content/plugins directory for the 'hydra-booking' or similar Themefic Hydra folderAffected if The Themefic Hydra Booking plugin is present and active in the WordPress installation
-
Identify installed plugin versionCheck the plugin header in the main plugin PHP file (typically contains 'Version:' comment) or view the plugin details in WordPress admin plugin listAffected if The installed version falls within any affected version range for this CVE
-
Test booking endpoints for unauthenticated accessAttempt to access booking management URLs or submit booking forms without logging in. Common paths include /wp-admin/admin-ajax.php actions related to booking, booking submission pages, or admin booking management areasAffected if Booking actions complete or admin functions respond without requiring login or returning an authorization error
-
Verify admin function authorizationIf you have low-privilege user accounts, attempt to access administrative functions within the Hydra Booking plugin (creating/editing bookings, managing settings) using a non-admin accountAffected if A standard subscriber or unauthenticated user can successfully perform administrative booking operations that should be restricted to administrators
-
Inspect AJAX action capability checksReview plugin source code for admin-ajax.php handlers. Search for 'add_action' calls on 'wp_ajax_' hooks and verify if each includes current_user_can() or similar capability checks before executing sensitive operationsAffected if AJAX actions related to booking management lack capability verification checks
You are affected if the Hydra Booking plugin is installed and sensitive booking/administrative functions are accessible without proper authentication or authorization validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper role-based access control (RBAC) and authorization checks on all sensitive functions and endpoints within the plugin, and update to version 1.1.42 or later if a patched version is available.
