TablePress, one of the most popular plugins for building and managing tables in WordPress sites, caught the attention of security researchers recently. It has been found with an exploitable vulnerability that puts millions of users at risk. This specific vulnerability is known as a Stored Cross-Site Scripting (XSS) vulnerability, and it affects all versions of the TablePress plugin up to, and including, 2.4.2. In this article, we will discuss the details of this vulnerability, its impact, mitigation, and provide a simple code snippet to help understand how this exploit works.

Vulnerability Details

The vulnerability, CVE-2024-9595, in TablePress plugin lies due to insufficient input sanitization and output escaping. This means that the attackers with at least Author-level access in a WordPress site using the vulnerable plugin version can inject arbitrary web scripts into the table cell content. These injected scripts will execute whenever any user accesses a page containing the affected table.

To understand this exploit better, let's consider a simple example. The attacker first has to log in with the target WordPress site's Author-level access or above. Once logged in, they can create a new table using the TablePress plugin by navigating to http://example.com/wp-admin/admin.php?page=tablepress&action=add. In the table cell content, the attacker can then inject a malicious JavaScript code, like the following one:

<script>alert('XSS Attack');</script>

Once this script is saved in the table cell content, it will execute automatically whenever a user visits a page with an injected table. This process can lead to the theft of sensitive information, such as login credentials, private messages, and other personal data.
