The Coupa Supplier Portal is a procurement platform used by organizations to manage spending and supplier contracts. A reflected cross-site scripting (XSS) vulnerability in the Tenders module allows a low-privileged attacker to craft a malicious link that, when clicked by a victim, executes arbitrary scripts in the victim's browser. An attacker could hijack the victim's session, access confidential procurement data, or perform unauthorized actions.

## Technical details

The `list_item_function` parameter in the Tenders module is reflected directly into a JavaScript event handler without output encoding or sanitization, enabling reflected XSS. An attacker with a low-privileged account can craft a malicious URL containing JavaScript payloads; the victim must click the link and be logged in for the script to execute in their browser context. A successful exploit allows session hijacking, information disclosure, and UI manipulation.
