# Coupa Supplier Portal: reflected script injection in Tenders module

A parameter named list_item_function in the Tenders module of Coupa Supplier Portal is echoed back into a page without encoding, inside a JavaScript event handler. An attacker who gets a victim to open a crafted link can run scripts in the victim's browser session, acting as that user.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

A reflected Cross-Site Scripting (XSS) vulnerability in the Tenders module of the Coupa Supplier Portal SaaS platform. The vulnerability arises because the `list_item_function` parameter is reflected in the server’s response without proper output encoding or sanitisation, and is directly embedded within the context of a JavaScript event handler. An attacker with a low-privileged account could create a malicious URL containing JavaScript payloads which, when opened by a victim, would execute arbitrary scripts within the context of the victim’s browser. A successful exploit could allow the attacker to perform actions on the victim’s behalf, disclose accessible information or manipulate the user interface.
