Title
Stored XSS in Participant URL Field leads to Account Takeover via Session Token Theft
Summary
Stored cross-site scripting in the participant URL handling in AWS Ops
Wheel before PR #168 might allow an authenticated remote user to steal
session tokens and escalate to full administrative control of the
deployed instance via a crafted participant_url value containing a
dangerous URI scheme.
To remediate this issue, users should redeploy from the latest version of aws-ops-wheel.
