Confirm relevance and assess potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending specially crafted requests over the network to a website using the vulnerable plugin. This bypasses the need for any special access or user interaction, directly targeting the input fields or parameters within the plugin. Successful exploitation could lead to unauthorized access to sensitive data or disruption of the affected application's database.

No authentication or user interaction needed.
Attacker sends malicious SQL commands.
Unauthorized data access or modification.

Frequently asked questions

What is the Learts Addons plugin used for?

Learts Addons is a software component designed for WordPress sites, typically used to extend the functionality of a theme by adding custom features or design elements. As a plugin, it integrates directly into the WordPress environment, which often makes it a core part of how a website handles user inputs and database interactions.

What does SQL injection mean for CVE-2025-59557?

This CVE involves a weakness classified as CWE-89, or SQL Injection. It occurs when a plugin fails to properly sanitize special characters in inputs before sending them to the database. Instead of treating data as plain text, the database may interpret malicious input as part of a command, allowing an attacker to query or interact with data they should not be able to access.

How does an attacker trigger this vulnerability?

An attacker triggers this flaw by sending specially crafted network requests that contain malicious SQL commands to the vulnerable plugin. This process does not require the attacker to have an account, special permissions, or any interaction from a legitimate user. It only works if the plugin is active and processing these specific, improperly handled inputs.

Is my site at risk if I use Learts Addons?

According to Halo Surface Signal, this vulnerability is considered likely to be reachable from the internet. Because WordPress plugins are commonly deployed on web-facing sites to provide public services, an attacker can generally target these installations remotely. If your site is public, it should be prioritized for review.

What should I do if I have this plugin installed?

Your first step is to locate all instances of Learts Addons within your WordPress environment to determine where it is running. Once identified, assess the business criticality of the affected sites. Work with your team to verify the current version in use and coordinate a plan to update the plugin or remove it if it is no longer required for your operations.
