What it is

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.
