pdfmake SVG Image Local File Read Vulnerability

Publication date: 2026-10-21

Last updated on: 2026-10-28

Assigner: VulnCheck

Description

pdfmake 0.3.8 before 0.3.12 fails to apply the setLocalAccessPolicy() restriction to images referenced inside SVG content, allowing attackers to read blocked local files. Attackers supplying a document definition can add an SVG image href pointing to a local path, embedding restricted file contents in the generated PDF.

Attack-Flow Graph

Executive Summary

This vulnerability affects pdfmake versions 0.3.8 to 0.3.11. It allows attackers to bypass the setLocalAccessPolicy() restriction for images inside SVG content. By including an SVG image with an href pointing to a local file path, attackers can embed restricted local files in the generated PDF.

Detection Guidance

Check the installed version of pdfmake using npm list pdfmake or by inspecting package.json. If the version is between 0.3.8 and 0.3.11, the system is vulnerable. Review SVG content in PDF generation for href attributes pointing to local file paths.

Impact Analysis

Attackers could exploit this to read files on your system that should be restricted. If you use pdfmake to generate PDFs from user-supplied content, malicious SVG images could expose sensitive local files in the output PDFs.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and confidentiality. Organizations using affected pdfmake versions may face compliance violations if local files containing personal or health data are exposed.

Mitigation Strategies

Upgrade pdfmake to version 0.3.12 or later immediately. If upgrading is not possible, disable SVG image processing or implement strict input validation for SVG href attributes to block local file paths.
