CVE-2024-10519·PHP vulnerability

The Wishlist for WooCommerce: Multi Wishlists Per Customer PRO plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'wtab' parameter in versions 3.0.8 to 3.1.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Note: Only WordPress installations with versions of PHP <=7.4 are affected by this vulnerability.

How likely is exploitation

FIRST's Exploit Prediction Scoring System puts the probability of this CVE being exploited in the next 30 days at 0.49% — higher than 39% of all published CVEs. EPSS is an independent forecast of exploitation, not a severity rating: it says nothing about how much damage a successful attack does, which is what a CVSS score measures.

Affected versions

From: 3.0.8

Until: 3.1.3

Fixed in: 3.1.3

How to fix this CVE

Update the Wishlist for WooCommerce plugin to version 3.1.3 or later, which includes proper input sanitization and output escaping for the 'wtab' parameter. If you are running PHP 7.4 or earlier on WordPress, prioritize this update immediately as older PHP versions are specifically vulnerable to this reflected XSS flaw. Verify the update was successful by checking the plugin version in your WordPress admin dashboard.

sudo dnf update php

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

GET.*wtab=.*(%3C|%3E|<|>|script|javascript|onerror|onload)

WAF mitigation (if patching is not yet possible)

Add this rule to your WAF to block exploitation attempts while you schedule the patch. 

Block or sanitize any request where the 'wtab' parameter contains HTML/JavaScript metacharacters (<, >, quotes, 'script', 'onerror', 'onload', etc.) or URL-encoded equivalents. Implement a WAF rule to enforce strict alphanumeric validation on the 'wtab' parameter only permitting expected tab identifiers.

How to check if you are affected

  1. Step 1: Check installed PHP version with `php -v` and note if it is version 7.4 or earlier
  2. Step 2: Log into WordPress admin, navigate to Plugins > Installed Plugins, and search for 'Wishlist for WooCommerce' to verify the current installed version
  3. Step 3: Search web server access logs (typically /var/log/apache2/access.log or /var/log/nginx/access.log) for requests containing 'wtab=' with URL-encoded special characters like '%3C', '%3E', or 'script'
  4. Step 4: After updating, re-check the plugin version in WordPress admin to confirm version 3.1.3 or higher is installed

FAQ

What is CVE-2024-10519?

This vulnerability is a reflected cross-site scripting (XSS) flaw in the Wishlist for WooCommerce plugin that allows attackers to inject malicious JavaScript through the 'wtab' parameter without proper sanitization, affecting WordPress sites running PHP 7.4 or earlier.

Is CVE-2024-10519 being actively exploited?

What versions of PHP are affected by CVE-2024-10519?

Only WordPress installations running PHP version 7.4 or earlier are affected; PHP 8.0 and later have mitigating factors that prevent exploitation.

How do I check if my server is vulnerable to CVE-2024-10519?

Run `php -v` to check your PHP version and `wp plugin list --field=name,version | grep 'wish-list'` (if WP-CLI is installed) to verify the Wishlist for WooCommerce version; vulnerability exists if PHP ≤7.4 and plugin is between 3.0.8–3.1.2.

Does Defensia detect CVE-2024-10519?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If PHP is installed on a monitored server, CVE-2024-10519 will appear in your dashboard with remediation steps.

CVE-2026-39337CVSS 10ChurchCRM is an open-source church management system. Prior to 7.1.0, critical pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The "$dbPassword" variable is not sanitized. This vulnerability exists due to an incomplete fix for CVE-2025-62521. This vulnerability is fixed in 7.1.0.
CVE-2026-28289CVSS 10FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. A patch bypass vulnerability for CVE-2026-27636 in FreeScout 1.8.206 and earlier allows any authenticated user with file upload permissions to achieve Remote Code Execution (RCE) on the server by uploading a malicious .htaccess file using a zero-width space character prefix to bypass the security check. The vulnerability exists in the sanitizeUploadedFileName() function in app/Http/Helper.php. The function contains a Time-of-Check to Time-of-Use (TOCTOU) flaw where the dot-prefix check occurs before sanitization removes invisible characters. This vulnerability is fixed in 1.8.207.
CVE-2025-46348CVSS 10YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.
CVE-2024-5932CVSS 10The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.14.1 via deserialization of untrusted input from the 'give_title' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code remotely, and to delete arbitrary files.
CVE-2025-47916CVSS 10Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.
