## What is CVE-2026-13119?

CVE-2026-13119 is a medium-severity SQL injection vulnerability in roundupwp Registrations for the Events Calendar – Event Registration Plugin, published on 23 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
