What is CVE-2026-35015?

The Open ISES Tickets application prior to version 3.44.2 is vulnerable to a reflected cross-site scripting (XSS) attack due to insufficient sanitization of user input in the 'the_ticket' GET parameter. This allows authenticated users to craft malicious URLs that can be used to deliver arbitrary JavaScript payloads executed in the context of another user's browser. If a victim unknowingly clicks on the crafted link, it could lead to session hijacking, data leakage, or other malicious actions facilitated by executing unauthorized scripts in the user's session.
