CVE-2026-13754 in Tickera Plugin
Summary
by MITRE • 07/16/2026
The Tickera – Sell Tickets & Manage Events plugin for WordPress is vulnerable to generic SQL Injection via the 's' parameter in all versions up to, and including, 3.6.0.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Tickera WordPress plugin vulnerability represents a critical security flaw that undermines the integrity of event management systems relying on this software. This generic SQL injection vulnerability exists within version 3.6.0.0 and all previous iterations, creating a persistent risk for organizations utilizing WordPress platforms for ticket sales and event coordination. The vulnerability stems from inadequate input sanitization practices where the 's' parameter fails to undergo proper escaping mechanisms before being incorporated into database queries.
The technical implementation of this flaw demonstrates a classic SQL injection vector that exploits insufficient query preparation and parameter validation. Attackers with authenticated access at the custom level or higher can manipulate the 's' parameter to inject malicious SQL commands into existing database queries. This vulnerability operates through the principle of concatenation where user-supplied input directly influences the constructed SQL statement without appropriate sanitization or parameter binding. The lack of proper input validation creates an environment where attackers can append additional SQL clauses that modify the original query's behavior.
From an operational perspective, this vulnerability presents significant risks to organizations managing event data and financial transactions through the Tickera plugin. Authenticated attackers can extract sensitive information including user credentials, event details, ticket sales data, and potentially payment information from the underlying database. The impact extends beyond simple data theft as attackers could manipulate query results to gain unauthorized access to restricted sections of the database or execute destructive operations. This vulnerability effectively undermines the trust model that WordPress plugins rely on for secure data handling.
The security implications align with CWE-89 which specifically addresses SQL injection vulnerabilities in software applications. This classification emphasizes the fundamental flaw in input handling where untrusted data enters an application through a vulnerable point and is processed without proper sanitization. The ATT&CK framework categorizes this issue under T1071.004 for application layer protocol, specifically targeting web application vulnerabilities that allow for data exfiltration and unauthorized access.
Mitigation strategies should focus on immediate patching of the Tickera plugin to version 3.6.1.0 or later where the SQL injection vulnerability has been addressed through proper input sanitization and query preparation mechanisms. Organizations must implement comprehensive access controls limiting administrative privileges to only essential personnel and regularly audit user permissions within their WordPress installations. Database query logging should be enabled to detect anomalous SQL patterns that might indicate exploitation attempts, while input validation routines should be strengthened to ensure all user-supplied parameters undergo proper escaping before database interaction. Additionally, implementing web application firewalls and intrusion detection systems can provide additional layers of protection against such attacks.
