The Snow Monkey Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'generate_user_dirpath' function in all versions up to, and including, 12.0.3. This vulnerability allows unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
With a critical CVSS score of 9.8, this vulnerability poses a significant risk. Organizations using the Snow Monkey Forms plugin should take immediate action to mitigate the risk, as the potential impact includes the loss of sensitive data and unauthorized access to the web server.
Currently, the vulnerability status is 'Awaiting Analysis'. However, it is crucial for organizations to understand the urgency of addressing this issue. Attackers may leverage this vulnerability to perform malicious actions on affected systems, making it essential to prioritize patching immediately.
The risk to organizations includes potential remote code execution, unauthorized access to sensitive files, and significant operational disruption. Therefore, organizations are encouraged to monitor their systems for any signs of exploitation.
Given the critical nature of this vulnerability, organizations should schedule remediation without delay to safeguard their systems.
Vulnerability Details
The Snow Monkey Forms plugin for WordPress is vulnerable due to insufficient file path validation in the 'generate_user_dirpath' function. The specific vulnerability is classified under CWE-22.
This vulnerability has a CVSS score of 9.8, indicating its critical severity. The attack vector is network-based, with low complexity, requiring no privileges or user interaction. The impacts on confidentiality, integrity, and availability are all classified as high.
The vulnerability was published on January 28, 2026, and is still awaiting further analysis by security teams.
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of file paths within the 'generate_user_dirpath' function. This oversight allows attackers to manipulate file paths and delete files that should not be accessible to them.
The attack vector is through network access, making it straightforward for remote attackers to exploit this vulnerability. The attack complexity is low, meaning that even those with minimal technical skills could potentially execute an exploit.
There are no privileges required for an attacker to exploit this vulnerability, and user interaction is not necessary. Given the high impacts on confidentiality, integrity, and availability, organizations using this plugin should be vigilant.
Risk & Impact Analysis
Organizations using the Snow Monkey Forms plugin face severe risks due to this vulnerability. The potential for remote code execution poses a significant threat, particularly if critical files such as wp-config.php are deleted.
The blast radius of such an exploitation could extend to the entire web application, leading to a complete compromise of sensitive data and system integrity. It is crucial for organizations to assess their exposure and implement necessary controls promptly.
The urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle. Failure to do so could result in significant financial and reputational damage.
