CVE-2026-13119: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in roundupwp Registrations for the Events Calendar – Event Registration Plugin
The Registrations For The Events Calendar plugin for WordPress is vulnerable to SQL Injection via JSON keys in the 'standard' parameter handled by the rtec_records_edit AJAX action in versions up to and including 3.2. The handler decodes attacker-controlled JSON from $_POST['standard'] and uses the JSON array keys directly as column identifiers in the SET clause of an UPDATE statement built inside RTEC_Db_Admin::update_entry(). Only esc_sql() (mysqli_real_escape_string) is applied to the identifier; that function escapes quotes, backslashes, and a few control characters but does not escape spaces, equals signs, parentheses, or hyphens, so an attacker can break out of the identifier context and inject subqueries (terminated with a SQL comment). This makes it possible for authenticated attackers, with Contributor-level access and above who can edit the targeted event, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
AI Analysis
Technical Summary
CVE-2026-13119 is an SQL Injection vulnerability in the Registrations For The Events Calendar plugin for WordPress, affecting versions up to and including 3.2. The issue occurs because the plugin decodes attacker-controlled JSON from the 'standard' POST parameter and uses the JSON array keys directly as column identifiers in an SQL UPDATE statement within RTEC_Db_Admin::update_entry(). The plugin applies only esc_sql() (mysqli_real_escape_string) to these identifiers, which does not sufficiently sanitize characters like spaces, equals signs, parentheses, or hyphens. This allows an authenticated attacker with Contributor-level privileges or higher to break out of the identifier context and inject subqueries terminated by SQL comments, enabling extraction of sensitive database information.
Potential Impact
An attacker with Contributor-level access or higher who can edit targeted events can exploit this vulnerability to perform SQL Injection attacks. This can lead to unauthorized disclosure of sensitive information from the database. The vulnerability does not affect confidentiality, integrity, or availability beyond data disclosure as per the CVSS vector (Confidentiality: High, Integrity: None, Availability: None).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level and higher access to trusted users only. Monitor for updates from the plugin vendor and apply patches promptly once released.
