CVE-2026-48231 is a SQL injection vulnerability in Open ISES Tickets prior to version 3.44.2. The issue exists in tables.php where POST parameters (tablename, indexname, sortby) are unsafely concatenated into dynamic SQL statements used for SELECT, UPDATE, and DELETE operations. Because these parameters are not sanitized, authenticated users can manipulate query semantics to access or alter database data beyond intended permissions. The vulnerability has a CVSS 4.0 base score of 7.1, reflecting high impact with network attack vector, low attack complexity, and no user interaction required.

Successful exploitation allows authenticated attackers to read, modify, or delete database contents by altering SQL query logic. This can lead to unauthorized data disclosure, data integrity loss, or denial of service through data destruction. The vulnerability affects confidentiality, integrity, and availability of the affected system's data.

No official patch or remediation guidance is currently available from the vendor. Users should monitor the vendor's advisories for updates and apply any forthcoming patches promptly. In the meantime, restricting access to trusted authenticated users and employing web application firewalls with SQL injection detection may help reduce risk. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
