CVE-2023-7076Network attack vector

Stored XSS via unescaped bug report fields

Published Dec 22, 2023 · Updated Nov 21, 2024

Stored cross-site scripting in OpenTibiaBR MyAAC 0.8.0 through 0.8.13 allows remote authenticated users to run script in a viewer's browser. bugtracker.php reads stored report subjects and text from the database and inserts them into HTML without calling escapeHtml. A low-privileged account can store the payload, but another user must view the affected bug report before browser-side execution occurs.
