CVE-2026-48247

Open ISES Tickets before 3.44.2 disables TLS certificate verification in incs/functions.inc.php by setting CURLOPT_SSL_VERIFYPEER to false (and not setting CURLOPT_SSL_VERIFYHOST) when issuing outbound HTTPS requests for general-purpose outbound HTTPS requests issued by the shared helper functions. 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.
