CVE-2026-15335
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 · uneditedThe Booking Package plugin for WordPress is vulnerable to generic SQL Injection via 'email' Form Parameter (form<N>) in all versions up to, and including, 1.7.20 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The vulnerable REST API endpoint /wp-json/booking-package/v1/request is registered with permission_callback: __return_true and wp_magic_quotes does not apply to REST-sourced $_POST values, meaning single quotes in the payload reach the SQL sink intact without any authentication requirement. The impact of this is severely limited as the vulnerable parameter goes through is_email.
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 · high confidenceThe Booking Package WordPress plugin versions up to 1.7.20 contain an unauthenticated SQL Injection vulnerability in the REST API endpoint /wp-json/booking-package/v1/request. The 'email' parameter is insufficiently escaped and reaches the SQL query without proper preparation. While the endpoint requires no authentication (permission_callback: __return_true), the impact is somewhat limited as the parameter passes through WordPress's is_email() validation.

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 Booking Package plugin installationIn WordPress admin, navigate to Plugins > Installed Plugins and locate 'Booking Package', or check the plugin files in wp-content/plugins/booking-package for a version file or header comment containing the version numberAffected if The plugin is installed and the version displayed is 1.7.20 or lower
-
Compare installed version to affected rangeReview the version number found - the vulnerable versions are up to and including 1.7.20. Versions 1.7.21 and later contain the patchAffected if The installed version is 1.7.20 or lower (for example, 1.7.19, 1.7.0, 1.6.5)
-
Verify the vulnerable REST API endpoint existsMake a GET request to /wp-json/booking-package/v1/request or attempt to access this endpoint using curl or a web browser. The endpoint should respond if the plugin is activeAffected if The endpoint responds with any JSON content, indicating the vulnerable API is accessible
-
Confirm the email parameter accepts inputSend a POST request to /wp-json/booking-package/v1/request with an 'email' parameter. Even though is_email() validation applies, the parameter should still accept and process inputAffected if The endpoint accepts the email parameter and processes it (response may vary based on other required parameters)
A user is affected if the Booking Package plugin is installed with version 1.7.20 or lower and the /wp-json/booking-package/v1/request REST API endpoint is accessible and accepting the email parameter.

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.
dbcve · scopedUpdate the Booking Package plugin to version 1.7.21 or later which contains the patched version. If an update is not immediately possible, consider disabling the plugin or implementing a WAF rule to block SQL injection attempts against the vulnerable endpoint.
Booking Package plugin version 1.7.21
- Upgrade the Booking Package plugin to version 1.7.21 or later, as the vulnerability is stated to exist in all versions up to and including 1.7.20
