Stored script execution via contact form fields
Published Jun 4, 2026 · Updated Jun 4, 2026
Stored cross-site scripting in Zuz Music 2.1 allows remote attackers to execute JavaScript in an administrator's browser via contact forms. The ___contact handler stores script-bearing name, subject, and message values, and the administrative inbox renders them as executable markup. No authentication is required to submit the payload, but an administrator must open the stored message; execution is limited to the browser context.
