CVE-2026-9507
Média · 5.1
CWE-38 16/06/2026
Session fixation vulnerability in Enhancesoft's osTicket
A session fixation vulnerability has been identified in osTicket v1.18.2. This security flaw allows an attacker to hijack a victim’s account by keeping the initial session identifier (OSTSESSID) active after a successful login.
The issue lies in the fact that the application does not invalidate the pre-authentication cookie or generate a new identifier for the authenticated context. As a result, if an attacker manages to set a known session identifier in the victim’s browser, they will be able to maintain unauthorised access to the account once the victim has authenticated.

Exploit público CWE-74 12/01/2026
osTicket (1.18.x < 1.18.3, 1.17.x < 1.17.7) PDF Export Arbitrary File Read
Enhancesoft osTicket versions 1.18.x prior to 1.18.3 and 1.17.x prior to 1.17.7 contain an arbitrary file read vulnerability in the ticket PDF export functionality. A remote attacker can submit a ticket containing crafted rich-text HTML that includes PHP filter expressions which are insufficiently sanitized before being processed by the mPDF PDF generator during export. When the attacker exports the ticket to PDF, the generated PDF can embed the contents of attacker-selected files from the server filesystem as bitmap images, allowing disclosure of sensitive local files in the context of the osTicket application user. This issue is exploitable in default configurations where guests may create tickets and access ticket status, or where self-registration is enabled.
