A vulnerability was detected in pskill9 website-downloader up to version 0.1.0. This vulnerability allows for an OS command injection due to improper handling of the outputPath argument in the download_website function located in the src/index.ts file. As a result, attackers may exploit this vulnerability remotely to execute arbitrary commands on the affected system.
This vulnerability has been assigned a CVSS score of 2.1, categorizing it as low severity. Despite its low score, the existence of a command injection vulnerability requires immediate attention from organizations utilizing this software. Currently, the exploit is public, indicating that it may be leveraged by attackers.
Organizations should prioritize patching immediately to prevent potential exploitation. The vendor has been informed of the issue through an issue report but has not yet responded, highlighting the urgency for users to take proactive measures to secure their systems.
In terms of remediation, affected users are advised to upgrade to a patched version of the software as soon as it becomes available. Monitoring and logging should also be enhanced to detect any unauthorized command execution attempts.
Vulnerability Details
The vulnerability affects the pskill9 website-downloader, specifically in the download_website function, where improper input handling of the outputPath leads to command injection opportunities. This vulnerability is classified under CWE-77 (Command Injection) and CWE-78 (OS Command Injection), reflecting its nature of allowing unauthorized command execution.
The CVSS score of 2.1 indicates a low severity level, which while not critical, still poses risks. The vulnerability was published on May 2, 2026, and remains unpatched as of the last update.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user input within the download_website function. The attack vector is network-based, allowing exploitation without direct access to the affected system. The attack complexity is low, and the required privileges are also low, making it easier for attackers to exploit this vulnerability.
There is no user interaction required for exploitation, which increases the risk of this vulnerability being leveraged in the wild. Confidentiality, integrity, and availability impacts are all rated as low, but the potential for command injection must not be underestimated.
Risk & Impact Analysis
Risk to organizations includes unauthorized command execution, which could lead to further exploitation of the system or sensitive data exposure. The impact radius is determined by the network exposure of the vulnerability, as an attacker could initiate exploitation from anywhere.
Given the CVSS score of 2.1 and active public knowledge of the vulnerability, organizations should address this vulnerability in their priority patch cycle. The urgency for organizations to remediate this flaw is highlighted by the presence of a public exploit.
