Over 100,000 WordPress Sites at Risk Due to Critical Wishlist Plugin Vulnerability

A critical security vulnerability has been identified in TI WooCommerce Wishlist plugin for WordPress Sites, potentially slashing over 100,000 websites. Considered a record holder with its full 10.0 score on the Common Vulnerability Scoring System (CVSS), this is indeed one almighty vulnerability under the tag of CVE-2025-47577.

Understanding the Vulnerability

TI WooCommerce Wishlist plugin faces widespread use amongst eCommerce institutes that let customers save and share their favorite products. Yet, the tinvwl_upload_file_wc_fields_factory function within the said plugin has a critical flaw. This function in turn uses WordPress Sites own native wp_handle_upload() function but flips the parameters test_form and test_type into false, thereby sidestepping the essential security checks. Malignant opportunity arises when unauthenticated users are allowed to arbitrarily upload files, including malicious PHP scripts, into the server.

Ensure you know that this vulnerability can only be exploited if the WC Fields Factory plugin is also installed and active on the site. The path traces potential remote code execution attacks formed in concert by these two plugins.

Recommended Actions for Website Administrators

Given the critical nature of this vulnerability and the current lack of an official patch, the following actions should be adopted immediately by website admins:

Deactivate and Remove the Plugin: Should your site be using the TI WooCommerce Wishlist plugin together with the WC Fields Factory plugin, it is safest to deactivate and remove both till a security update is released.

Suspicious Activities Monitoring: Be on the lookout for any unusual activity reported in your server logs and file directories or even unauthorized file uploads.

Establish WAFs: Web Application Firewalls should be implemented and configured to detect and block any malicious traffic, forging to exploit the known vulnerabilities.

Updates and Information: Subscribe to security bulletins and updates from trustworthy sources to stay aware of the latest threats and best practices.

Fortifying WordPress Security

Strengthening your website from such threats entails the following:

Keep Everything Updated: This means all plugins, themes, and WordPress Sites core in itself; the moment a security patch is issued, it needs to be applied.

Salt Down on Plugin Usage: Until the plugin is needed, use it carefully, and if one from a questionable source, best to avoid it altogether; get rid of the ones you no longer use.

File Permissions and Security: Keeping the files safe with secured permissions; not easy for unauthorized storage or modification.

Periodic Backups: Backups daily, weekly, or whichever preferred interval; there’s no choice if a breach happens-and recovery is a must.
