Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) in Biobanking and Biomolecular Resources Negotiator v3.15.2. It occurs because the application does not properly validate user input sent via a POST request to the '/api/v3/negotiations/<postUID>/posts' endpoint using the 'text' parameter. This allows a remote attacker to inject malicious scripts that are stored and later executed in the context of authenticated users.

Impact Analysis

An attacker exploiting this vulnerability could send a specially crafted query to an authenticated user, potentially stealing their session cookie details. This could lead to session hijacking, unauthorized access to user accounts, and further compromise of the affected system.
