Zuz Music 2.1 Persistent Cross-site Scripting via zuzconsole Contact

Published Jun 4, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
Zuz Music 2.1 contains a persistent cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious JavaScript by submitting crafted contact form data. Attackers can inject script code through the name, subject, and message parameters in POST requests to /gmusic/zuzconsole/___contact, which executes when administrators view messages in the inbox interface.

Analysis

AI-generated

Technical impact

The vulnerability is a persistent cross‑site scripting flaw that allows unauthenticated users to embed and store malicious JavaScript snippets in the contact form fields. These scripts reside in the message database and execute when an administrator opens the message in the inbox interface. This exposure originates from improper input validation on the name, subject, and message parameters of the /gmusic/zuzconsole/___contact endpoint (CWE‑79).

Affected Systems

Affected by this flaw are installations of Zuz Music version 2.1. No other versions are known to be impacted. The vendor is Zuz, and the product is the Zuz Music platform.

Risk and Exploitability

The CVSS score is 5.3, indicating a medium severity. EPSS is not available and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires only the ability to submit a crafted contact request; it does not need admin credentials to inject the payload, but the effect materializes only after an administrator views the message. Consequently, the risk is moderate and primarily concerns admins who routinely access the inbox.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Verify if Zuz has released a security update for Zuz Music 2.1 and apply it when available.
  • Apply custom server‑side sanitization or escaping for the name, subject, and message fields in the /gmusic/zuzconsole/___contact endpoint.
  • Restrict the contact form to authenticated users or require administrator approval before messages are stored.
  • Monitor the admin inbox for unexpected content and review logs for suspicious activity.
