## Affected

- Coupa Coupa Total Spend Management Platform: fixed in 04/11/2026

## Description

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.
