What is CVE-2026-8194?

A security flaw has been identified in the osTicket software prior to version 1.18.4, particularly within the Dispatcher component's include/class.dispatcher.php file. This vulnerability arises from improper handling of the _method argument, allowing for cross-site request forgery (CSRF) attacks. A remote attacker could exploit this weakness to manipulate requests on behalf of logged-in users, thereby potentially exposing sensitive data or executing unintended actions. This issue has been publicly disclosed, and the osTicket project has yet to issue a substantive response, despite being informed through a pull request.

Affected Version(s)

osTicket 1.18.0

osTicket 1.18.1

osTicket 1.18.2

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
