CVE-2025-7050: Use-your-Drive WordPress Plugin XSS Flaw

CVE-2025-7050 Overview

A Stored Cross-Site Scripting (XSS) vulnerability has been identified in the Use-your-Drive | Google Drive plugin for WordPress in all versions up to and including 3.3.1. The vulnerability exists in the title parameter within file metadata due to insufficient input sanitization and output escaping. This flaw allows attackers to inject arbitrary web scripts into pages that execute whenever a user accesses an injected page. Critically, the vulnerability can be exploited by unauthenticated users when a file upload shortcode is published on a publicly accessible post.

Critical Impact

Unauthenticated attackers can inject persistent malicious scripts through file metadata, potentially compromising administrator sessions, stealing credentials, or distributing malware to all site visitors.

Affected Products

• Use-your-Drive | Google Drive plugin for WordPress versions up to and including 3.3.1
• WordPress sites utilizing the plugin's file upload shortcode on public pages
• Sites allowing unauthenticated file uploads through the plugin

Technical Details for CVE-2025-7050

Vulnerability Analysis

This Stored Cross-Site Scripting vulnerability (CWE-79) resides in the Use-your-Drive plugin's handling of file metadata, specifically within the title parameter. When files are uploaded through the plugin, the file title metadata is stored without proper sanitization. Subsequently, when this metadata is displayed to users browsing the file listings, the malicious script payload executes in the context of the victim's browser session.

The vulnerability is particularly dangerous because it requires no authentication to exploit when a file upload shortcode is publicly accessible. Once a malicious file with a crafted title is uploaded, the injected script persists in the system and executes for every user who views the page containing the file listing—including site administrators.

Root Cause

The root cause of CVE-2025-7050 is the failure to implement proper input sanitization and output escaping for user-controlled file metadata. The plugin accepts the title parameter from uploaded files without validating or sanitizing the content for potentially dangerous HTML or JavaScript code. When this unsanitized data is later rendered in the browser, it is interpreted as executable code rather than plain text, enabling script injection.

Attack Vector

The attack exploits the network-accessible file upload functionality exposed through WordPress shortcodes. An attacker crafts a file with a malicious JavaScript payload embedded in the file's title metadata. When uploaded through a publicly accessible form, this payload is stored in the WordPress database. The attack requires no user interaction beyond normal page visits—any user accessing the page with the file listing will have the malicious script execute in their browser context.

The attack flow typically follows this pattern: First, the attacker identifies a WordPress site using the vulnerable plugin with public file uploads enabled. The attacker then prepares a file with a specially crafted title containing JavaScript code. Upon upload, the malicious title is stored without sanitization. Finally, when administrators or visitors view the file listing, the stored XSS payload executes, potentially stealing session cookies, redirecting to phishing pages, or performing actions on behalf of the victim.

Detection Methods for CVE-2025-7050

Indicators of Compromise

• Presence of JavaScript code or HTML tags in file metadata titles within the plugin's database entries
• Unexpected script execution or browser console errors when viewing file listings
• User reports of suspicious redirects or pop-ups when accessing pages with the plugin's file browser
• Anomalous file uploads with unusual or obfuscated title names containing special characters

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block XSS payloads in file upload parameters
• Monitor server logs for suspicious file upload requests containing script tags or encoded JavaScript
• Perform regular database audits searching for stored XSS patterns in plugin-related tables
• Deploy client-side Content Security Policy (CSP) headers to mitigate script execution from injected content

Monitoring Recommendations

• Enable verbose logging for file upload activities on WordPress sites using this plugin
• Configure alerts for file uploads containing suspicious patterns in metadata fields
• Monitor for unusual administrator session activity that could indicate session hijacking
• Implement real-time threat intelligence feeds to identify known XSS attack patterns

How to Mitigate CVE-2025-7050

Immediate Actions Required

• Update the Use-your-Drive | Google Drive plugin to the latest patched version immediately
• Audit existing file uploads and database entries for potentially malicious metadata content
• Temporarily disable public file upload functionality until the patch is applied
• Review and restrict file upload permissions to authenticated users only where possible

Patch Information

The vendor has released security updates to address this vulnerability. Refer to the WP Cloud Plugins Changelog for the latest version information and patch details. Additional technical analysis is available in the Wordfence Vulnerability Report.

Organizations should prioritize applying the vendor-provided patch as it addresses the underlying input sanitization and output escaping deficiencies that enable this attack.

Workarounds

• Remove or disable public-facing file upload shortcodes until a patch can be applied
• Implement server-side input validation to strip HTML and JavaScript from file metadata before storage
• Deploy strict Content Security Policy headers to prevent inline script execution
• Restrict file upload capabilities to authenticated and trusted users only

# Example: Add Content Security Policy header in .htaccess as a temporary mitigation
# This helps prevent execution of injected inline scripts
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none';"
