CVE-2026-15335

Low risk38th percentile - higher than 38% of all known CVEs
Summary
The Booking Package plugin for WordPress up to version 1.7.20 is vulnerable to generic SQL injection via the 'email' form parameter (form<N>). Insufficient escaping and lack of query preparation allow unauthenticated attackers to append additional SQL queries, potentially extracting sensitive database information.
Risk Assessment
The risk involves unauthorized database access and potential leakage of sensitive information, such as user data or content, without authentication. The impact is limited because the parameter is validated by is_email.
Recommendation
Immediately update the Booking Package plugin to the latest version that fixes this vulnerability. If an update is not possible, temporarily disable the plugin or apply WAF rules to block suspicious requests to the REST API endpoint.
Other vulnerabilities in Booking Package
See all- CVE-2026-16986Medium
The Booking Package WordPress plugin before version 1.7.25 does not validate the payment amount server-side against the stored service price, deriving the expected charge from attacker-supplied request values instead, so an unauthenticated attacker can pay an arbitrary fraction of a service's real price.
- CVE-2026-40774High
The Booking package versions <= 1.7.06 have an issue with unauthenticated access that allows for broken access control.
- CVE-2026-9851High
A vulnerability in the Booking Package plugin for WordPress up to version 1.7.16 allows privilege escalation via account takeover. Missing capability checks in the package_app_action AJAX endpoint let authenticated attackers with Editor-level access or above change the email and password of any account, including administrators.
Original NVD description (English source)
The 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.
