Technical details
The PeproDev Ultimate Invoice plugin for WordPress is vulnerable to Reflected Cross-Site Scripting (XSS) due to improper neutralization of user-supplied input during web page generation (CWE-79). An unauthenticated remote attacker can exploit this by sending a specially crafted request to a vulnerable site. If a victim (such as a site administrator) interacts with the malicious link or page, the attacker's script will execute in the context of the victim's browser session. This can result in session hijacking, unauthorized administrative actions, or website defacement. As of the advisory date, no official patch has been released, and users are advised to seek mitigation through security rules or alternative plugins.
