CVE-2025-6262: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in museai skiv video embedding
The muse.ai video embedding plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's muse-ai shortcode in all versions up to, and including, 0.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-6262 is a stored cross-site scripting vulnerability in the muse.ai video embedding WordPress plugin (skiv video embedding) affecting all versions up to 0.4. The issue is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-supplied attributes in the muse-ai shortcode. Authenticated attackers with contributor or higher privileges can inject malicious scripts that execute in the context of users viewing the compromised pages. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting medium severity with network attack vector, low complexity, and no user interaction needed. No patch or vendor advisory is currently available to confirm remediation status.
Potential Impact
Successful exploitation allows authenticated contributors or higher to inject and store malicious scripts within WordPress pages using the muse-ai shortcode. These scripts execute in the browsers of users who view the infected pages, potentially leading to theft of session tokens, defacement, or other client-side impacts. The vulnerability does not affect availability and requires authenticated access with contributor or higher privileges. No known exploits are reported in the wild.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory for updates on remediation. Until a fix is released, restrict contributor-level access to trusted users only and consider disabling the muse.ai video embedding plugin if possible to prevent exploitation.
