CVE-2024-13793 in Wolmart Plugin
Summary
by MITRE • 05/08/2025
The Wolmart | Multi-Vendor Marketplace WooCommerce Theme theme for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.8.11. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

The vulnerability identified as CVE-2024-13793 affects the Wolmart WooCommerce theme version 1.8.11 and earlier, representing a critical security flaw that undermines the integrity of WordPress-based e-commerce platforms. This issue resides within the theme's handling of shortcode execution mechanisms, where insufficient input validation creates an exploitable condition that allows malicious actors to manipulate the system's behavior. The vulnerability specifically targets the theme's implementation of do_shortcode functionality, which serves as a core WordPress mechanism for processing and executing custom shortcode attributes. When users interact with the theme's interface, particularly through frontend elements that process shortcode parameters, the system fails to properly sanitize or validate the input values before executing the do_shortcode function.
The technical exploitation of this vulnerability occurs through unauthenticated attack vectors that leverage the theme's lack of proper validation controls. Attackers can craft malicious shortcode parameters that, when processed by the vulnerable theme, execute arbitrary code within the WordPress environment. This represents a classic case of insufficient input validation that aligns with CWE-20, which describes weaknesses in input validation that allow for injection attacks. The vulnerability's impact extends beyond simple code execution as it provides attackers with the ability to manipulate the theme's functionality, potentially leading to unauthorized access, data manipulation, or even complete system compromise depending on the permissions granted to the theme's execution context.
The operational implications of this vulnerability are severe for online marketplaces that rely on the Wolmart theme, as it creates an entry point for attackers to compromise entire store infrastructures. Unauthenticated attackers can exploit this weakness without requiring valid user credentials, making the attack surface particularly dangerous for public-facing e-commerce sites. The vulnerability affects all versions up to 1.8.11, indicating a widespread exposure across numerous installations that may not have received timely updates or patches. This situation creates a significant risk for marketplace operators who may unknowingly expose their platforms to exploitation, potentially leading to customer data breaches, financial losses, and reputational damage. The attack vector typically involves manipulating shortcode parameters through GET or POST requests that are processed by the theme's frontend handlers, where the lack of proper sanitization allows attackers to inject malicious shortcode content.
Organizations affected by this vulnerability should implement immediate mitigation strategies to protect their systems while planning for proper patching. The primary recommendation involves updating to the latest available version of the Wolmart theme that addresses this specific vulnerability, as this represents the most effective long-term solution. Security teams should also consider implementing web application firewalls that can detect and block suspicious shortcode parameter patterns, particularly those that attempt to execute known malicious shortcode functions. Additionally, administrators should review and restrict shortcode usage permissions within the WordPress environment, limiting which roles can create or modify content that may contain shortcodes. The vulnerability's classification under ATT&CK technique T1059.008 for 'Command and Scripting Interpreter: PowerShell' and T1190 for 'Exploit Public-Facing Application' highlights the need for comprehensive security monitoring and response protocols. Organizations should also conduct thorough security assessments of their WordPress installations to identify any other potential vulnerabilities that may exist within the same theme or related plugins, as this type of weakness often indicates broader security gaps in the implementation.
