Detailsinfo

A vulnerability, which was classified as critical, was found in roundupwp Events Calendar Plugin up to 3.2. This affects the function RTEC_Db_Admin::update_entry of the component rtec_records_edit AJAX Action. The manipulation of the argument standard with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at wordfence.com. This vulnerability is uniquely identified as CVE-2026-13119 since 06/23/2026. The exploitability is told to be easy.
