Executive Summary

This is a stored cross-site scripting (XSS) vulnerability in AWS Ops Wheel before PR #168. It allows an authenticated remote user to inject malicious code via a crafted participant_url value with a dangerous URI scheme. This could lead to session token theft and full administrative control of the instance.

Detection Guidance

This vulnerability involves stored cross-site scripting in AWS Ops Wheel via crafted participant_url values. Detection requires inspecting web application logs for unusual participant URLs containing dangerous URI schemes or JavaScript payloads. Check for requests or inputs with participant_url parameters containing suspicious patterns like 'javascript:', 'data:', or encoded scripts.
