Description

Stored cross-site scripting (XSS) in the HTML report generator in the aidlc-traceability CLI in AWS AI-DLC Workflows before 2026-07-03 might allow an actor who can modify a project's AI-DLC artifact files to execute arbitrary script in the browser of a user who opens a generated HTML traceability report via crafted artifact titles or descriptions.
