CVE-2025-62907Network attack vector

Contributor-level stored script execution via unescaped content

Published Oct 27, 2025 · Updated Oct 27, 2025

Stored cross-site scripting in aviplugins.com Custom Post Type Attachment 3.4.6 and earlier allows remote authenticated users to inject scripts. The public CNA and vendor records attribute the flaw to insufficient input sanitization and output escaping but do not disclose the affected parameter, function, or storage path. Contributor-level access is required, and the stored payload executes when another user visits the affected page, allowing it to read page-accessible data or perform actions available to that browser session.
