How to Fix CVE-2024-4367

To remediate this vulnerability, upgrade all affected Pdfjs dist dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

pdfjs-dist fixed: 4.2.67 
npm install pdfjs-dist@4.2.67
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls pdfjs-dist

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-4367, inspect your project dependencies using npm:

npm ls pdfjs-dist

Analyze the terminal output to locate any version of Pdfjs dist in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.2.67), your application is affected.

Note: The npm ls pdfjs-dist command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-754: Improper Check for Unusual or Exceptional Conditions, where the product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the product. In Pdfjs dist, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact If pdf.js is used to load a malicious PDF, and PDF.js is configured with `isEvalSupported` set to `true` (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain. ### Patches The patch removes the use of `eval`: https://github.com/mozilla/pdf.js/pull/18015 ### Workarounds Set the option `isEvalSupported` to `false`. ### References https://bugzilla.mozilla.org/show_bug.cgi?id=1893645
