This vulnerability, identified as CWE-89, affects Nexcess Event Tickets versions up to and including 5.29.5. It is an SQL Injection issue in the Contributor component, where special elements in SQL commands are not properly neutralized. The CVSS 3.1 score is 8.5, indicating high severity with network attack vector, low attack complexity, low privileges required, no user interaction, and scope changed. The impact includes high confidentiality impact and low availability impact, with no integrity impact. There is no information about known exploits or vendor patches.

An attacker with low privileges can exploit this SQL Injection vulnerability remotely to execute unauthorized SQL commands. This can lead to unauthorized disclosure of sensitive information (high confidentiality impact) and partial disruption of service (low availability impact). Integrity is not impacted according to the CVSS vector. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor Nexcess advisories for updates. Until a fix is available, restricting contributor privileges and applying web application firewall rules to detect and block SQL injection attempts may help mitigate risk.
