CVE-2026-48248: Open Ises Tickets

Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days.

Open ISES Tickets before 3.44.2 disables TLS certificate verification in incs/login.inc.php by setting CURLOPT_SSL_VERIFYPEER to false (and not setting CURLOPT_SSL_VERIFYHOST) when issuing outbound HTTPS requests issued during the login/authentication flow. An attacker positioned on the network path between the server and the remote endpoint can present a forged certificate to intercept, monitor, or modify the request and response, including any API keys or session-bearing data in transit.
