Cross-site scripting (XSS) vulnerabilities have become increasingly common in modern web applications, posing significant risks to users and organizations alike. The latest version of the Beekeeper Studio application, v3.6.6, has been found to be susceptible to an XSS vulnerability that allows attackers to execute arbitrary web scripts or HTML via a crafted payload inserted into the error modal container. This blog post will explore the details of this vulnerability (CVE-2022-43143), explain how it works, provide examples of how it can be exploited, and offer recommendations to help defend against this attack vector.

Beekeeper Studio: An Overview

Beekeeper Studio is an open-source SQL editor and database management tool available for Windows, macOS, and Linux platforms. It supports a variety of databases, such as MySQL, PostgreSQL, SQLite, and more. This powerful tool offers an elegant and modern user interface, making it a popular choice for many developers and database administrators.

You can find the official source code repository of Beekeeper Studio on GitHub:

The Vulnerability: How it Works

The XSS vulnerability in Beekeeper Studio v3.6.6 allows attackers to execute arbitrary web scripts or HTML via a specially crafted payload injected into the error modal container. Specifically, when the application encounters an error, it displays a modal window with the error details. The vulnerability arises when the application fails to properly sanitize user input, allowing an attacker to inject malicious code via the payload.

Below is a code snippet that demonstrates this vulnerability

// Function to handle displaying error messages in Beekeeper Studio
function showError(errorDetails) {
  // ... other code ...

  // Get the modal container to display the error details
  const modalContainer = document.getElementById("error-modal");

  // Inject the error message into the container
  // Note: The input is not sanitized, allowing for XSS vulnerabilities
  modalContainer.innerHTML = errorDetails;

  // Display the error modal
  // ... other code ...

Exploiting the Vulnerability

To exploit this vulnerability, an attacker must craft a payload containing a malicious web script or HTML, then find a way to inject this payload into the error modal container.

For example, an attacker could create a payload that looks like this

  // Arbitrary JavaScript code the attacker wants to execute
  console.log("XSS attack executed.");

Once the attacker has crafted their payload, they must trigger an error within the application to display the error modal. When the error modal is displayed, the malicious script within the payload will execute, allowing the attacker to perform various attacks, such as stealing sensitive information or redirecting users to phishing websites.

Mitigation and Recommendations

To defend against this vulnerability, developers should follow best practices for web application security, such as input validation and output encoding.

To mitigate the XSS vulnerability in Beekeeper Studio, one possible solution would be to sanitize user input before inserting it into the error modal container. In this case, developers could use a library like DOMPurify to cleanse the input of any potentially malicious code. This would prevent arbitrary web scripts and HTML from being executed within the error modal.

Additionally, developers and users should keep their applications up-to-date with the latest security patches, as XSS vulnerabilities can have severe consequences if left unaddressed.


This blog post examined the details of the CVE-2022-43143 XSS vulnerability found in Beekeeper Studio v3.6.6, which allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the error modal container. By understanding how this vulnerability works, its potential impacts, and ways to mitigate its risks, developers and users can better protect their applications, systems, and data from potential XSS attacks.
