The ML Responsive Audio player with playlist Shortcode by ersatzpole suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that can affect confidentiality, integrity, and availability to a limited extent. The affected versions include all versions up to and including 0.2. No patch or vendor advisory is currently provided.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, modification of content, or denial of service. The CVSS vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with partial impact on confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or limiting use of the affected plugin. Applying web application firewall (WAF) rules to detect and block XSS payloads may provide temporary mitigation. Avoid granting unnecessary privileges to users who can input data into the plugin.
