Publication date: 2026-08-25

Last updated on: 2026-08-25

Assigner: VulDB

Description
A vulnerability was detected in Fdawgs node-poppler up to 9.1.2/10.0.1. The impacted element is the function pdfInfo/pdfToText/pdfToCairo/pdfToPpm/pdfImages/pdfToHtml/pdfToPs/pdfFonts/pdfDetach/pdfAttach/pdfSeparate/pdfUnite of the file src/index.js of the component Argument Injection Handler. Performing a manipulation of the argument file_path results in argument injection. The attack may be initiated remotely. The patch is named db6e3f79d3beb20601be7e59669c39811ae3c330. It is recommended to apply a patch to fix this issue.

CWE ID Description
CWE-88 The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-78637 is an argument injection vulnerability in the node-poppler library up to version 9.1.2/10.0.1. It occurs when file paths starting with a hyphen are passed to Poppler utilities without validation. This allows attackers to inject malicious command-line options, causing the tools to misinterpret filenames as switches and potentially exit prematurely.

Detection Guidance

To detect this vulnerability, check if your node-poppler version is 9.1.2 or below. Run 'npm list node-poppler' to verify the installed version. If vulnerable, look for unusual command-line arguments in logs or process monitoring tools that show file paths starting with hyphens being passed to poppler-utils tools.

Impact Analysis

This vulnerability could allow attackers to manipulate file paths to inject options like -v or -listenc, causing Poppler tools to print information and exit without processing the intended file. While remote code execution is not possible, it may mislead applications into believing files were processed successfully.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by allowing unauthorized manipulation of file paths, which may lead to improper handling of sensitive data. Argument injection could cause applications to process files incorrectly or expose unintended information, violating data integrity and confidentiality requirements.

Mitigation Strategies

Update node-poppler to the latest patched version using 'npm update node-poppler'. If updating is not possible, apply the patch from commit db6e3f79d3beb20601be7e59669c39811ae3c330 manually. Ensure input validation for file paths to reject those starting with hyphens or normalize them by prefixing with './'.
