How to fix

Fixed in: commit 96cf0ea (2026-07-03); tool subsequently removed from awslabs/aidlc-workflows on 2026-07-16

Do not open HTML reports generated by an unpatched copy of the tool from untrusted projects. Use Markdown report output instead of HTML, or regenerate reports only from artifact files you control, until you update or remove the local copy.

Technical details

Stored XSS in the HTML report generator where unsanitized artifact titles and descriptions are embedded into HTML without proper escaping, allowing script injection via crafted artifact metadata. The vulnerability requires an attacker with write access to project artifact files; users viewing the generated HTML report from untrusted projects are at risk. The fix (commit 96cf0ea, 2026-07-03) sanitizes embedded JSON and hardens file-read boundaries.
