Background
The pdf-image npm package is a popular library used for extracting images from PDF files. It provides functionality to convert PDF pages into images. The package is widely used in various applications that require PDF processing. However, versions of pdf-image up to 2.0.0 are vulnerable to an improper input validation and code injection vulnerability.
Vulnerability Detail
The vulnerability arises due to a lack of input validation in the pdf-image npm package. If the PDF file path is constructed based on untrusted user input, an attacker can exploit this vulnerability to execute arbitrary code. This can lead to various malicious activities, such as remote code execution, unauthorized access, and data manipulation. The vulnerability has a severity score of 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The Common Weakness Enumeration (CWE) IDs associated with this vulnerability are CWE-20 (Improper Input Validation) and CWE-94 (Code Injection).
How To Fix
No fixed version is published for this vulnerability.

Workaround
If updating the package is not immediately feasible, a temporary workaround is to avoid constructing file paths based on untrusted user input. Instead, use a predefined and trusted file path for PDF files. This can help mitigate the risk of code injection.
Conclusion
The pdf-image npm package up to version 2.0.0 is vulnerable to an improper input validation and code injection vulnerability. This can allow an attacker to execute arbitrary code, leading to severe consequences such as remote code execution and unauthorized access. It is crucial for developers to update the package to a secure version and implement proper input validation to mitigate the risk.
