CVE-2026-56059
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSubscriber Arbitrary File Upload in Travel Booking <= 2.2.5 versions.
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 confidenceThe Travel Booking plugin allows authenticated users with Subscriber role to upload arbitrary files to the server due to insufficient validation and sanitization of uploaded files. This enables an attacker with minimal privileges to upload malicious PHP files or other executable content.

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.
-
Identify Travel Booking plugin and versionLocate the Travel Booking plugin in your WordPress installation (wp-content/plugins/) and read the main plugin file header to obtain the installed version number.Affected if the installed version is older than the latest patched version (if known) or if you cannot confirm it has been patched
-
Verify if subscriber registration is enabledIn WordPress admin, go to Settings > General and check if the option 'Anyone can register' is set to Subscriber, or inspect the site registration settings via database or REST API.Affected if subscriber role registration is enabled, allowing external users to obtain subscriber-level access
-
Check subscriber role capabilitiesUse a role management plugin or WP-CLI command: wp user role list to examine if the Subscriber role has been granted upload_file, edit_files, or similar file-handling capabilities beyond the default.Affected if subscriber role possesses upload or file management capabilities
-
Inspect plugin file upload functionalityReview the Travel Booking plugin code, specifically any file upload handlers or forms that accept file submissions, to determine if the upload mechanism validates file types and content.Affected if the plugin contains file upload functionality that does not validate file types or sanitize filenames before storage
You are affected if the Travel Booking plugin is installed with an unpatched version AND subscriber registration is enabled, allowing any visitor to register as a subscriber and exploit the file upload vulnerability.

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 dataUpdate Travel Booking to the latest patched version. Until patched, disable subscriber registration or remove file upload capabilities from subscriber accounts.
