High severity GitHub Reviewed Published Oct 11, 2019 to the GitHub Advisory Database • Updated Feb 1, 2023

Package

npm html-pdf (npm)

Affected versions

< 3.0.1

Patched versions

3.0.1

Description

All versions of html-pdf are vulnerable to Arbitrary File Read. The package fails to sanitize the HTML input, allowing attackers to exfiltrate server files by supplying malicious HTML code. XHR requests in the HTML code are executed by the server. Input with an XHR request such as request.open("GET","file:///etc/passwd") will result in a PDF document with the contents of /etc/passwd.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
