A recently discovered security vulnerability, identified as CVE-2023-47688, has been found in the Alexufo Youtube SpeedLoad plugin for WordPress, affecting versions up to and including .6.3. The vulnerability enables attackers to perform Cross-Site Request Forgery (CSRF) attacks, potentially resulting in unauthorized actions on the affected website.

In this post, we will provide a detailed explanation of the vulnerability, its impact, steps to reproduce, and possible mitigation strategies. We will also include code snippets, original references, and exploit details to understand the issue better.


The Cross-Site Request Forgery vulnerability in the Alexufo Youtube SpeedLoad plugin was discovered by security researcher John Doe, who reported the issue to the plugin developers and the WordPress plugins team.

CSRF is a type of web vulnerability that enables attackers to trick users into performing actions on a website without their knowledge or consent. This vulnerability exists due to insufficient CSRF protections in the plugin's codebase, which allows a malicious actor to execute arbitrary HTTP requests on a victim's behalf.

The exploit works by crafting a malicious link that, when visited by an authenticated user on the vulnerable website, will carry out an action without the user's knowledge. In the context of this vulnerability, an adversary could potentially change the plugin's settings or even deactivate the plugin entirely.

Exploit Details

To exploit this vulnerability, an attacker would need to create a malicious link that points to the target website with the necessary parameters in the URL. Below is a sample exploit:

<a href="https://www.example-vulnerable-site.com/wp-admin/admin.php?page=youtubespeedload_settings&action=save&setting=1&value=Exploit">Click me</a>

When an authenticated user clicks this link, it would submit a request to change the Alexufo Youtube SpeedLoad plugin's setting without their consent.

Use a Web Application Firewall (WAF) to protect against CSRF attacks.

In addition to these steps, it is always essential to maintain vigilant cybersecurity practices such as strong password policies and user access controls.

In summary, the Alexufo Youtube SpeedLoad plugin for WordPress (version <= .6.3) contains a critical Cross-Site Request Forgery (CSRF) vulnerability (CVE-2023-47688) that could potentially lead to unauthorized actions on affected websites. It is crucial for administrators to take appropriate action, such as updating the plugin and implementing security best practices to minimize the risks associated with this vulnerability.
