Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Jason Judge CSV Importer Improved allows Stored XSS. This issue affects CSV Importer Improved: from n/a through 0.6.1.
AnalysisAI
Stored cross-site scripting (XSS) in CSV Importer Improved WordPress plugin up to version 0.6.1 allows authenticated users with high privileges to inject malicious scripts via imported CSV data. The vulnerability is triggered when an administrator views the imported data, leading to script execution in the admin context. No public exploit or active exploitation has been identified, and the EPSS score is low (0.04%).
Technical ContextAI
The vulnerability is a stored XSS (CWE-79) in the CSV Importer Improved plugin for WordPress. The plugin fails to sanitize or escape data imported from CSV files before rendering it in the WordPress admin interface. This allows an attacker with high privileges (e.g., admin) to upload a crafted CSV containing JavaScript payloads. When another admin views the imported data, the script executes in their browser session. The CVSS vector indicates a network attack vector, low complexity, high privileges required, user interaction required, and scope change (confidentiality, integrity, availability low).
RemediationAI
Update CSV Importer Improved to version 0.6.2 or later, which contains the fix. The vendor advisory from Patchstack confirms the patch. As a workaround, restrict the ability to import CSV files to trusted administrators only, and avoid viewing imported data from untrusted sources. No other compensating controls are recommended due to the low risk.
