Severity

7.3 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N

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.
