## Technical details

A reflected cross-site scripting (XSS) vulnerability exists in OTRS 7.0.x and OTRS Community Edition 6.x and earlier due to improper neutralization of user-controllable input. The flaw is located within the ticket handling component, specifically affecting request parameters associated with ticket actions. An attacker can craft a malicious URL containing JavaScript; when an authenticated agent visits this link, the script executes within the context of their session. This can lead to unauthorized actions being performed on behalf of the agent or the theft of session tokens. While the CVSS vector indicates no privileges are required (PR:N), the attack relies on user interaction (UI:R) from an authenticated agent to be successful.
