Key points

The flaw is rated CVSS 9.3 Critical and involves improper neutralization of SQL commands.
Affected software includes Tickera versions from the initial release through 3.6.0.6.
The vulnerability allows for blind SQL injection, potentially exposing sensitive database information.

The National Vulnerability Database recorded CVE-2026-105889, identifying a critical security flaw in the Tickera event ticketing system. This vulnerability allows attackers to execute blind SQL injection attacks against installations running version 3.6.0.6 or earlier. The issue stems from improper neutralization of special elements within SQL commands.

At a glance

CVE: CVE-2026-105889
Product: Tickera
CVSS: 9.3 Critical
Weakness: SQL injection
Exploited: No known exploitation

Security researchers assigned a CVSS score of 9.3, classifying the severity as Critical. The weakness is categorized under CWE-89, which denotes SQL Injection vulnerabilities. Attackers can exploit this flaw to manipulate database queries without seeing the direct output, a technique known as blind SQL injection. This method can still lead to significant data exposure or system compromise.

Context and Background

SQL injection remains one of the most common web application vulnerabilities. It occurs when user input is not properly sanitized before being included in an SQL statement. In this specific case, the Tickera application failed to neutralize special elements used in SQL commands. This oversight creates an entry point for malicious actors to inject their own code.

Blind SQL injection is particularly dangerous because it does not require the application to display the results of the query. Attackers can infer data by observing changes in the application's behavior or response times. This makes detection more difficult for administrators who rely on visible error messages to identify potential breaches.

Who Is Affected

The vulnerability affects all versions of the Tickera event ticketing system up to and including version 3.6.0.6. According to the NVD record, the issue exists from the initial release through the specified version. Organizations using this software for event management and ticket sales are at risk.

Users who have not updated their installations remain exposed to this attack vector. The widespread use of event ticketing platforms makes this a high-priority fix for many businesses. Failure to address the issue could result in unauthorized access to customer data and transaction records.

What should you do?

Administrators should immediately verify their current version of the Tickera event ticketing system. If the installation is version 3.6.0.6 or older, it is vulnerable to this critical flaw. Users should check for vendor updates or patches that address CVE-2026-105889. Until a fix is confirmed, limiting access to the application may reduce risk.

What to do and how to stay safe: Tickera

Audit your environment to identify any installations of Tickera event ticketing software.
Check the current version number to see if it falls within the affected range up to 3.6.0.6.
Monitor vendor communications for the release of a security patch or update.
Implement strict input validation and web application firewalls to mitigate SQL injection risks.
