CVE-2025-24490 - Mattermost SQL Injection Vulnerability in Board Reordering

A new security vulnerability has been identified in Mattermost, an open-source messaging platform for IT teams. The vulnerability, which has been assigned the identifier CVE-2025-24490, affects several versions of Mattermost, including 10.4.x <= 10.4.1, 9.11.x <= 9.11.7, 10.3.x <= 10.3.2, and 10.2.x <= 10.2.2.

The vulnerability involves improper usage of SQL queries in the process of reordering boards categories, which makes it possible for an attacker to execute SQL injection attacks. SQL injection attacks enable the retrieval of sensitive data from the database, thus posing significant security risks.

In this post, we will discuss in detail the exploit details as well as available patches and workarounds.

Exploit Details

A vulnerability has been identified in the Mattermost server's logic for handling boards categories reordering. Specifically, the server fails to use prepared statements during the SQL query execution process. As a result, malicious users can inject crafty SQL codes that then get executed by the Mattermost server. This ultimately enables unauthorized access to the database, posing a considerable threat to user privacy and security.

Let's take a look at a code snippet demonstrating the issue

# Vulnerable code snippet
def reorder_categories(category_order: List[str]) -> None:
    # ...
    for index, category_id in enumerate(category_order):
        # SQL Injection vulnerability here
        cursor.execute(f"UPDATE boards_category SET position = {index} WHERE id = '{category_id}'")
    # ...

In this code snippet, the cursor.execute function directly executes a SQL query that concatenates the user input with the query string without using prepared statements. This makes it possible to execute the injected SQL code.

The attacker gains unauthorized access to sensitive data in the database.

Available Patches and Workarounds

Mattermost developers have acknowledged this vulnerability and have released updates to address the issue. The patches for the affected versions can be downloaded from the following links:

- Mattermost 10.4.2
- Mattermost 9.11.8
- Mattermost 10.3.3
- Mattermost 10.2.3

Users are strongly encouraged to update their Mattermost instances as soon as possible.

As a temporary workaround, system administrators can restrict the access permissions for users who do not require the ability to reorder boards categories until the proper patch is applied.

Conclusion

It is essential to keep software up-to-date and follow best security practices, especially when dealing with sensitive data such as user information. By regularly patching your systems and being aware of potential threats, you can ensure the safe and secure operation of your software. Stay vigilant, and ensure your systems are patched to mitigate the risks posed by vulnerabilities such as CVE-2025-24490.
