CVE-2026-48241: Hardcoded MySQL Credentials in Open ISES Tickets Expose Data

CVE-2026-48241: Hardcoded MySQL Credentials in Open ISES Tickets Expose Data

The National Vulnerability Database has disclosed CVE-2026-48241, a high-severity vulnerability (CVSS 8.1) affecting Open ISES Tickets versions prior to 3.44.2. The issue stems from hardcoded MySQL database credentials embedded directly within loader.php, a publicly accessible database utility. These credentials, including username, password, and database name, are committed to the source repository.

This is a critical misstep. Any attacker with access to the public source tree or even unauthenticated read access to the loader.php file on a deployed installation can easily extract these credentials. If the database is reachable from the attacker’s network, they can connect directly, bypassing standard authentication and gaining full access to the underlying data. This isn’t theoretical; it’s a direct path to data compromise.

For defenders, the implications are stark. Hardcoded credentials are a gift to attackers, eliminating the need for complex exploits. Organizations running Open ISES Tickets must immediately upgrade to version 3.44.2 or later. Post-patch, it’s imperative to rotate any database credentials that were previously hardcoded, as they are now compromised by public disclosure.

What This Means For You

  • If your organization uses Open ISES Tickets, assume your database credentials are compromised if you haven't upgraded to version 3.44.2. Patch immediately and, more importantly, revoke and replace the hardcoded MySQL credentials from your database server. This isn't just about patching the application; it's about invalidating the exposed secret.
